+
+### Key Features Implemented
+
+✅ **Template System**
+- Dynamic template selection based on request type and user role
+- Configurable tabs, headers, and quick actions
+- Role-based access control at template and tab level
+
+✅ **IO Tab for Dealer Claims**
+- Fetch IO budget from SAP
+- Block budget in SAP system
+- Display blocked IO details
+- Release blocked budget
+
+✅ **Three Built-in Templates**
+1. Standard Template - Default workflow requests
+2. Dealer Claim Template - Claim management with IO integration
+3. Vendor Template - Vendor purchase orders and invoices
+
+✅ **Backward Compatibility**
+- Original `RequestDetail` component remains unchanged
+- Existing implementations continue to work
+- New template system is opt-in
+
+## 🚀 Quick Start
+
+### Step 1: Use the New Template-Driven Component
+
+```tsx
+// For dealer claims (auto-selects dealerClaim template)
+import { RequestDetailTemplated } from '@/pages/RequestDetail';
+
+// In your route or component
+<RequestDetailTemplated 
+  requestId="RE-REQ-2024-CM-100"
+  onBack={() => navigate('/dashboard')} 
+/>
+```
+
+### Step 2: Configure Template Selection
+
+Update your request data model to include category/type:
+
+```typescript
+// Backend: Add category field to requests
+{
+  requestId: "RE-REQ-2024-CM-100",
+  title: "Dealer Claim Request",
+  category: "claim-management",  // ← This triggers dealerClaim template
+  claimAmount: 1000,
+  // ... other fields
+}
+```
+
+### Step 3: Update Routes (Optional)
+
+```tsx
+// src/routes/AppRoutes.tsx or similar
+import { RequestDetailTemplated } from '@/pages/RequestDetail';
+
+// Replace old route
+<Route path="/request/:requestId" element={<RequestDetailTemplated />} />
+
+// Or keep both for migration period
+<Route path="/request/:requestId" element={<RequestDetail />} />
+<Route path="/request-v2/:requestId" element={<RequestDetailTemplated />} />
+```
+
+## 📋 Implementation Steps by User Type
+
+### For Dealers (Claim Management)
+
+**Backend Setup:**
+
+```csharp
+// .NET API: Ensure request model includes necessary fields
+public class DealerClaimRequest
+{
+    public string RequestId { get; set; }
+    public string Category { get; set; } = "claim-management";
+    public string Type { get; set; } = "dealer-claim";
+    public decimal ClaimAmount { get; set; }
+    public string IoNumber { get; set; }
+    public decimal? IoBlockedAmount { get; set; }
+    // ... other fields
+}
+```
+
+**Frontend Usage:**
+
+```tsx
+// Automatically uses dealerClaim template
+<RequestDetailTemplated requestId={claimRequestId} />
+
+// Shows these tabs:
+// 1. Overview
+// 2. Workflow (8-Steps)
+// 3. IO (Budget Management) ← NEW!
+// 4. Documents
+// 5. Activity
+// 6. Work Notes
+```
+
+**SAP Integration:**
+
+The IO tab includes placeholders for SAP integration. Implement these API endpoints:
+
+```typescript
+// src/services/sapApi.ts
+
+/**
+ * Fetch IO budget from SAP
+ */
+export async function fetchIOBudget(ioNumber: string): Promise<IOBudgetResponse> {
+  const response = await apiClient.get(`/api/sap/io/${ioNumber}/budget`);
+  return response.data;
+}
+
+/**
+ * Block budget in SAP
+ */
+export async function blockIOBudget(request: BlockBudgetRequest): Promise<BlockBudgetResponse> {
+  const response = await apiClient.post('/api/sap/io/block', request);
+  return response.data;
+}
+
+/**
+ * Release blocked budget
+ */
+export async function releaseIOBudget(ioNumber: string, documentNumber: string): Promise<void> {
+  await apiClient.post('/api/sap/io/release', { ioNumber, documentNumber });
+}
+```
+
+**.NET API Endpoints:**
+
+```csharp
+// Controllers/SapController.cs
+
+[ApiController]
+[Route("api/sap")]
+public class SapController : ControllerBase
+{
+    private readonly ISapService _sapService;
+
+    [HttpGet("io/{ioNumber}/budget")]
+    public async Task<ActionResult<IOBudgetResponse>> GetIOBudget(string ioNumber)
+    {
+        var budget = await _sapService.GetAvailableBudget(ioNumber);
+        return Ok(budget);
+    }
+
+    [HttpPost("io/block")]
+    public async Task<ActionResult<BlockBudgetResponse>> BlockBudget([FromBody] BlockBudgetRequest request)
+    {
+        var result = await _sapService.BlockBudget(
+            request.IoNumber, 
+            request.Amount, 
+            request.RequestId
+        );
+        return Ok(result);
+    }
+
+    [HttpPost("io/release")]
+    public async Task<ActionResult> ReleaseBudget([FromBody] ReleaseBudgetRequest request)
+    {
+        await _sapService.ReleaseBudget(request.IoNumber, request.DocumentNumber);
+        return Ok();
+    }
+}
+```
+
+### For Vendors
+
+```tsx
+// Request with vendor category
+<RequestDetailTemplated requestId="VEND-2024-001" />
+
+// Backend: Set category
+{
+  category: "vendor",
+  // or
+  type: "vendor"
+}
+```
+
+### For Standard Users
+
+```tsx
+// Regular workflow requests
+<RequestDetailTemplated requestId="REQ-2024-001" />
+
+// Uses standard template by default
+```
+
+## 🎨 Creating Custom Templates
+
+### Example: Create a Marketing Campaign Template
+
+```tsx
+// src/pages/RequestDetail/templates/marketingTemplate.ts
+
+import { RequestDetailTemplate } from '../types/template.types';
+import { OverviewTab } from '../components/tabs/OverviewTab';
+import { WorkflowTab } from '../components/tabs/WorkflowTab';
+import { CampaignDetailsTab } from '../components/tabs/CampaignDetailsTab'; // Your custom tab
+
+export const marketingTemplate: RequestDetailTemplate = {
+  id: 'marketing',
+  name: 'Marketing Campaign',
+  description: 'Template for marketing campaign approvals',
+
+  tabs: [
+    {
+      id: 'overview',
+      label: 'Overview',
+      icon: ClipboardList,
+      component: OverviewTab,
+      order: 1,
+    },
+    {
+      id: 'campaign',
+      label: 'Campaign Details',
+      icon: Star,
+      component: CampaignDetailsTab,
+      order: 2,
+    },
+    {
+      id: 'workflow',
+      label: 'Workflow',
+      icon: TrendingUp,
+      component: WorkflowTab,
+      order: 3,
+    },
+  ],
+
+  defaultTab: 'overview',
+
+  header: {
+    showBackButton: true,
+    showRefreshButton: true,
+  },
+
+  quickActions: {
+    enabled: true,
+    customActions: [
+      {
+        id: 'schedule',
+        label: 'Schedule Campaign',
+        icon: Calendar,
+        action: async (context) => {
+          // Custom action logic
+        },
+        visible: (context) => context.request?.status === 'approved',
+      },
+    ],
+  },
+
+  layout: {
+    showQuickActionsSidebar: true,
+    fullWidthTabs: [],
+  },
+
+  canAccess: (user, request) => {
+    return user?.role === 'marketing' || user?.role === 'admin';
+  },
+};
+```
+
+### Register the Template
+
+```tsx
+// src/pages/RequestDetail/templates/index.ts
+
+import { marketingTemplate } from './marketingTemplate';
+
+export const templateRegistry: TemplateRegistry = {
+  standard: standardTemplate,
+  dealerClaim: dealerClaimTemplate,
+  vendor: vendorTemplate,
+  marketing: marketingTemplate, // ← Add here
+};
+
+// Update selector
+export const selectTemplate: TemplateSelector = (user, request, routeParams) => {
+  if (request?.category === 'marketing-campaign') {
+    return 'marketing';
+  }
+  
+  if (request?.category === 'claim-management') {
+    return 'dealerClaim';
+  }
+  
+  // ... other logic
+  
+  return 'standard';
+};
+```
+

+
+## 🚀 How to Use
+
+### For Dealers (Claim Management)
+
+```tsx
+import { RequestDetailTemplated } from '@/pages/RequestDetail';
+
+// Backend: Set category
+{
+  requestId: "RE-REQ-2024-CM-100",
+  category: "claim-management",  // ← Triggers Dealer Claim Template
+  claimAmount: 1000
+}
+
+// Frontend: Use component
+<RequestDetailTemplated requestId="RE-REQ-2024-CM-100" />
+
+// Result: Shows IO tab with SAP budget management
+```
+
+### For Standard Requests
+
+```tsx
+// Backend: Regular request
+{
+  requestId: "REQ-2024-001",
+  category: "standard"
+}
+
+// Frontend: Same component
+<RequestDetailTemplated requestId="REQ-2024-001" />
+
+// Result: Shows standard tabs
+```
+
+### Create Custom Template

+# Request Detail Template System - Quick Reference
+
+## 🚀 Quick Start
+
+### Use Template-Driven Component
+
+```tsx
+import { RequestDetailTemplated } from '@/pages/RequestDetail';
+
+// Auto-selects template based on request type
+<RequestDetailTemplated requestId="REQ-123" />
+
+// Explicit template selection
+<RequestDetailTemplated requestId="REQ-123" template="dealerClaim" />
+```
+
+## 📋 Built-in Templates
+
+| Template ID | Use Case | Key Features |
+|------------|----------|--------------|
+| `standard` | Default workflows | Overview, Workflow, Documents, Activity, Work Notes, Summary |
+| `dealerClaim` | Dealer claims | All standard + **IO Budget Management** |
+| `vendor` | Vendor requests | Overview, Workflow, Documents, Activity, Work Notes |
+
+## 🎯 Template Selection Logic
+
+Templates are auto-selected based on:
+
+```typescript
+// Request category
+request.category === 'claim-management' → dealerClaim
+request.category === 'vendor' → vendor
+
+// Request type
+request.type === 'dealer-claim' → dealerClaim
+
+// User role
+user.role === 'vendor' → vendor
+
+// Default
+→ standard
+```
+
+## 🔧 Create Custom Template
+
+### 1. Define Template
+
+```tsx
+// templates/myTemplate.ts
+export const myTemplate: RequestDetailTemplate = {
+  id: 'myCustom',
+  name: 'My Custom Template',
+  description: 'Description',
+  
+  tabs: [
+    {
+      id: 'overview',
+      label: 'Overview',
+      icon: ClipboardList,
+      component: OverviewTab,
+      order: 1,
+    },
+    // Add more tabs...
+  ],
+  
+  defaultTab: 'overview',
+  
+  header: {
+    showBackButton: true,
+    showRefreshButton: true,
+  },
+  
+  quickActions: {
+    enabled: true,
+  },
+  
+  layout: {
+    showQuickActionsSidebar: true,
+    fullWidthTabs: [],
+  },
+  
+  canAccess: (user, request) => true,
+};
+```
+
+### 2. Register Template
+
+```tsx
+// templates/index.ts
+import { myTemplate } from './myTemplate';
+
+export const templateRegistry = {
+  standard: standardTemplate,
+  myCustom: myTemplate, // ← Add here
+};
+```
+
+### 3. Update Selector
+
+```tsx
+// templates/index.ts
+export const selectTemplate = (user, request) => {
+  if (request?.type === 'my-type') return 'myCustom';
+  return 'standard';
+};
+```
+
+## 📄 Create Custom Tab
+
+```tsx
+// components/tabs/MyTab.tsx
+export function MyTab({ request, user, refreshDetails }: any) {
+  return (
+    <Card>
+      <CardHeader>
+        <CardTitle>My Custom Tab</CardTitle>
+      </CardHeader>
+      <CardContent>
+        <p>Request: {request?.requestId}</p>
+        <Button onClick={refreshDetails}>Refresh</Button>
+      </CardContent>
+    </Card>
+  );
+}
+```
+
+## 🎨 Tab Configuration Options
+
+```typescript
+{
+  id: 'myTab',                    // Unique ID
+  label: 'My Tab',                // Display label
+  icon: Star,                     // Lucide icon
+  component: MyTabComponent,       // React component
+  order: 3,                       // Display order
+  visible: (ctx) => true,         // Visibility function
+  badge: (ctx) => 5,             // Badge count
+}
+```
+
+## 🔒 Access Control
+
+### Template Level
+
+```typescript
+canAccess: (user, request) => {
+  const allowedRoles = ['admin', 'dealer'];
+  return allowedRoles.includes(user?.role);
+}
+```
+
+### Tab Level
+
+```typescript
+{
+  id: 'admin',
+  label: 'Admin',
+  icon: Shield,
+  component: AdminTab,
+  visible: (context) => context.user?.role === 'admin',
+}
+```
+
+## 💡 Common Patterns
+
+### Conditional Tab Visibility
+
+```typescript
+// Show only for closed requests
+visible: (ctx) => ctx.isClosed
+
+// Show only for initiators
+visible: (ctx) => ctx.isInitiator
+
+// Show only for high-value requests
+visible: (ctx) => (ctx.request?.amount || 0) > 100000
+
+// Show only for specific roles
+visible: (ctx) => ['admin', 'finance'].includes(ctx.user?.role)
+```
+
+### Custom Quick Actions
+
+```typescript
+quickActions: {
+  enabled: true,
+  customActions: [
+    {
+      id: 'myAction',
+      label: 'My Action',
+      icon: Zap,
+      action: async (context) => {
+        // Your logic here
+        toast.success('Action completed!');
+      },
+      visible: (context) => context.isInitiator,
+      variant: 'default',
+    },
+  ],
+}
+```
+
+### Badge Notifications
+
+```typescript
+{
+  id: 'messages',
+  label: 'Messages',
+  icon: MessageSquare,
+  component: MessagesTab,
+  badge: (context) => context.unreadMessages || null,
+}
+```
+
+## 📦 Template Context API
+
+All tab components receive `TemplateContext`:
+
+```typescript
+{
+  // Data
+  request: any;
+  apiRequest?: any;
+  user: any;
+  
+  // State
+  isInitiator: boolean;
+  isSpectator: boolean;
+  isClosed: boolean;
+  needsClosure: boolean;
+  
+  // Actions
+  refreshDetails: () => Promise<void>;
+  onApprove: () => void;
+  onReject: () => void;
+  onPause: () => void;
+  onResume: () => void;
+  
+  // Additional
+  unreadWorkNotes: number;
+  summaryDetails: any;
+  // ... more
+}
+```
+
+## 🎯 IO Tab (Dealer Claims)
+
+### Features
+
+```
+1. Fetch IO Budget from SAP
+   ↓
+2. Validate Against Claim Amount
+   ↓
+3. Block Budget in SAP
+   ↓
+4. Display Blocked Details
+   ↓
+5. Release Budget (if needed)
+```
+
+### Backend Integration
+
+```csharp
+// .NET API Endpoints
+GET  /api/sap/io/{ioNumber}/budget
+POST /api/sap/io/block
+POST /api/sap/io/release
+```
+
+### Frontend Usage
+
+```tsx
+// Automatic for dealer claims
+<RequestDetailTemplated 
+  requestId="RE-REQ-2024-CM-100"  // Dealer claim
+/>
+
+// Backend: Set category
+{
+  category: "claim-management",
+  claimAmount: 1000
+}
+```
+

+# Claim Management Integration Guide
+
+This guide explains how the RequestDetail page has been refactored to support both regular workflow requests and Claim Management requests with role-based visibility.
+
+## Architecture Overview
+
+### Component Structure
+
+```
+src/pages/RequestDetail/
+├── components/
+│   ├── claim-cards/              # Modular cards for claim management
+│   │   ├── ActivityInformationCard.tsx
+│   │   ├── DealerInformationCard.tsx
+│   │   ├── ProposalDetailsCard.tsx
+│   │   ├── ProcessDetailsCard.tsx
+│   │   ├── RequestInitiatorCard.tsx
+│   │   └── index.ts
+│   └── tabs/
+│       ├── ClaimManagementOverviewTab.tsx  # Claim-specific overview
+│       └── OverviewTab.tsx                  # Regular overview (existing)
+├── types/
+│   ├── claimManagement.types.ts   # Type definitions for claims
+│   └── requestDetail.types.ts      # Existing types
+├── utils/
+│   └── claimDataMapper.ts          # Data transformation utilities
+└── RequestDetail.tsx               # Main component
+```
+
+## Key Features
+
+### 1. **Modular Card Components**
+
+Each section of the claim management UI is a separate, reusable component:
+
+- **ActivityInformationCard**: Activity details, budget, expenses
+- **DealerInformationCard**: Dealer contact and location info
+- **ProposalDetailsCard**: Dealer's cost breakup and timeline
+- **ProcessDetailsCard**: IO, DMS, Claim Amount, Budget breakdowns
+- **RequestInitiatorCard**: Initiator information (shared component)
+
+### 2. **Role-Based Visibility**
+
+Visibility is controlled by the user's role:
+
+```typescript
+export type RequestRole = 
+  | 'initiator' 
+  | 'dealer' 
+  | 'department_lead' 
+  | 'finance' 
+  | 'spectator' 
+  | 'approver';
+```
+
+**Key Rules:**
+- **Dealers CANNOT see IO details** (budget information)
+- **Internal RE users** (Initiator, Dept Lead, Finance) can see everything
+- **Spectators** have read-only access to all information
+
+### 3. **Data Mapping Layer**
+
+The `claimDataMapper.ts` utility transforms API responses to strongly-typed claim structures:
+
+```typescript
+// Automatically detect claim management requests
+const isClaim = isClaimManagementRequest(apiRequest);
+
+// Map API data to claim structure
+const claimRequest = mapToClaimManagementRequest(apiRequest, userId);
+
+// Determine user's role
+const userRole = determineUserRole(apiRequest, userId);
+
+// Get visibility settings
+const visibility = getRoleBasedVisibility(userRole);
+```
+
+## Integration Steps
+
+### Step 1: Update RequestDetail.tsx
+
+Replace the existing overview tab rendering with the adaptive approach:
+
+```typescript
+import { AdaptiveOverviewTab } from './components/tabs/ClaimManagementOverviewTab';
+import { OverviewTab } from './components/tabs/OverviewTab';
+
+// Inside RequestDetail component
+<TabsContent value="overview" className="mt-0">
+  <AdaptiveOverviewTab
+    request={request}
+    apiRequest={apiRequest}
+    currentUserId={(user as any)?.userId}
+    isInitiator={isInitiator}
+    onEditClaimAmount={() => {
+      // Handle claim amount editing
+      setShowEditClaimAmountModal(true);
+    }}
+    // Fallback to regular overview for non-claim requests
+    regularOverviewComponent={OverviewTab}
+    regularOverviewProps={{
+      request,
+      isInitiator,
+      needsClosure,
+      conclusionRemark,
+      setConclusionRemark,
+      conclusionLoading,

+      currentUserId: (user as any)?.userId,
+    }}
+  />
+</TabsContent>
+```
+
+### Step 2: API Data Structure
+
+Ensure your API returns claim data in this structure:
+
+```typescript
+{
+  requestId: "RE-REQ-2024-CM-100",
+  requestType: "claim_management",  // or templateType, workflowType
+  title: "Activity Name",
+  status: "in_progress",
+  claimData: {
+    activityName: "dasds",
+    activityType: "Promotional Event",
+    location: "Mumbai",
+    requestedDate: "2025-12-11",
+    estimatedBudget: 1000,
+    closedExpenses: 800,
+    period: {
+      startDate: "2025-12-10",
+      endDate: "2025-12-15"
+    },
+    description: "Activity description",
+    closedExpensesBreakdown: [
+      { description: "hhh", amount: 800 }
+    ],
+    dealerInfo: {
+      dealerCode: "RE-MH-001",
+      dealerName: "Royal Motors Mumbai",
+      email: "dealer@royalmotorsmumbai.com",
+      phone: "+91 98765 12345",
+      address: "Shop No. 12-15, Central Avenue, Mumbai"
+    },
+    proposalDetails: {
+      costBreakup: [
+        { description: "1wdw", amount: 1000 }
+      ],
+      timelineForClosure: "2025-12-09",
+      dealerComments: "Comments here",
+      submittedOn: "2025-12-05T09:32:00Z",
+      estimatedBudgetTotal: 1000
+    },
+    ioDetails: {
+      ioNumber: "dfdf",
+      remarks: "dfdf",
+      blockedBy: "user123",
+      blockedByName: "Priya Sharma",
+      blockedAt: "2025-12-05T09:34:00Z",
+      availableBalance: 50000,
+      blockedAmount: 1000,
+      remainingBalance: 49000
+    },
+    dmsDetails: {
+      dmsNumber: "DMS1764907715200392",
+      remarks: "hjj",
+      createdBy: "dealer456",
+      createdByName: "Royal Motors Mumbai",
+      createdAt: "2025-12-05T09:38:00Z"
+    },
+    claimAmount: {
+      amount: 1000,
+      editable: true,
+      lastUpdatedBy: "Priya Sharma",
+      lastUpdatedAt: "2025-12-05T09:40:00Z"
+    }
+  }
+}
+```
+
+### Step 3: Role Detection
+
+The system automatically detects the user's role based on:
+
+1. **Initiator**: `createdBy === userId`
+2. **Dealer**: `claimData.dealerInfo.userId === userId`
+3. **Department Lead**: Role in approval flow
+4. **Finance**: Role in approval flow
+5. **Spectator**: In spectators list
+6. **Approver**: Any approver in approval flow
+
+### Step 4: Conditional Rendering
+
+Components automatically show/hide based on visibility rules:
+
+```typescript
+const visibility = getRoleBasedVisibility(userRole);
+
+// Dealers will have:
+visibility.showIODetails = false;       // Cannot see IO details
+visibility.showDMSDetails = true;       // Can see DMS
+visibility.showClaimAmount = true;      // Can see amount
+visibility.canEditClaimAmount = false;  // Cannot edit
+
+// Department Leads will have:
+visibility.showIODetails = true;        // Can see IO details
+visibility.canEditClaimAmount = true;   // Can edit claim amount
+```
+
+## Benefits of This Architecture
+
+### 1. **Modularity**
+Each card component is independent and can be:
+- Reused in different contexts
+- Easily tested in isolation
+- Modified without affecting others
+
+### 2. **Type Safety**
+Strong TypeScript types ensure:
+- Correct data structures
+- Role-based access enforcement
+- Compile-time error detection
+
+### 3. **Maintainability**
+- Clear separation of concerns
+- Single Responsibility Principle
+- Easy to add new request types
+
+### 4. **Flexibility**
+- Supports multiple request types
+- Role-based visibility
+- Easy to extend with new roles or sections
+
+## Usage Examples
+
+### Example 1: Render Only Activity Information
+
+```typescript
+import { ActivityInformationCard } from '@/pages/RequestDetail/components/claim-cards';
+
+<ActivityInformationCard 
+  activityInfo={{
+    activityName: "Campaign Event",
+    activityType: "Marketing",
+    location: "Delhi",
+    requestedDate: "2025-12-15",
+    estimatedBudget: 50000
+  }}
+/>
+```
+
+### Example 2: Conditional Process Details
+
+```typescript
+import { ProcessDetailsCard } from '@/pages/RequestDetail/components/claim-cards';
+import { getRoleBasedVisibility } from '@/pages/RequestDetail/types/claimManagement.types';
+
+const visibility = getRoleBasedVisibility('dealer');
+
+<ProcessDetailsCard
+  ioDetails={ioData}          // Won't show because dealer
+  dmsDetails={dmsData}        // Will show
+  claimAmount={claimAmount}   // Will show but not editable
+  visibility={visibility}
+/>
+```
+
+### Example 3: Standalone Dealer Card
+
+```typescript
+import { DealerInformationCard } from '@/pages/RequestDetail/components/claim-cards';
+
+<DealerInformationCard
+  dealerInfo={{
+    dealerCode: "RE-MH-001",
+    dealerName: "Royal Motors",
+    email: "contact@dealer.com",
+    phone: "+91 12345 67890",
+    address: "Mumbai, India"
+  }}
+/>
+```
+
+## Testing Considerations
+
+### Unit Tests
+
+Test each card component independently:
+
+```typescript
+describe('ActivityInformationCard', () => {
+  it('should render activity details', () => {
+    // Test rendering
+  });
+  
+  it('should format currency correctly', () => {
+    // Test formatting
+  });
+  
+  it('should show breakdown when provided', () => {
+    // Test conditional rendering
+  });
+});
+```
+
+### Integration Tests
+
+Test role-based visibility:
+
+```typescript
+describe('ClaimManagementOverviewTab', () => {
+  it('should hide IO details for dealers', () => {
+    // Test dealer view
+  });
+  
+  it('should show all details for initiators', () => {
+    // Test initiator view
+  });
+});
+```
+
+## Migration Path
+
+### For Existing Requests
+
+The system is backward compatible:
+- Non-claim requests continue to use `OverviewTab`
+- Claim requests automatically use `ClaimManagementOverviewTab`
+- No data migration required
+
+### Adding New Request Types
+
+To add a new custom request type:
+
+1. Create type definitions in `types/`
+2. Create card components in `components/custom-cards/`
+3. Create overview tab in `components/tabs/`
+4. Update `AdaptiveOverviewTab` to detect and route
+
+## Troubleshooting
+
+### Issue: IO Details Showing for Dealers
+
+**Cause**: Role detection incorrect  
+**Solution**: Verify `dealerInfo.userId` is set correctly in API response
+
+### Issue: Components Not Rendering
+
+**Cause**: Missing claim data in API response  
+**Solution**: Ensure `claimData` object exists in API response
+
+### Issue: Wrong Role Detected
+
+**Cause**: User ID mismatch  
+**Solution**: Check that `currentUserId` matches API user IDs
+
+## Next Steps
+
+1. **Implement Edit Claim Amount Modal**
+2. **Add Workflow-Specific Components** (8-step workflow visualization)
+3. **Create Dealer Submission Forms** (Proposal, Completion Documents)
+4. **Add IO Management Interface** (for Department Leads)
+5. **Implement DMS Integration UI**

+# Request Detail Template System
+
+## Overview
+
+The Request Detail template system provides a flexible, reusable architecture for displaying and managing different types of workflow requests. It supports multiple user types (dealers, vendors, standard users) with customizable tabs, layouts, and behaviors.
+
+## Architecture
+
+```
+RequestDetail/
+├── templates/
+│   ├── index.ts                    # Template registry and selector
+│   ├── standardTemplate.ts         # Standard workflow template
+│   ├── dealerClaimTemplate.ts      # Dealer claim management template
+│   └── vendorTemplate.ts           # Vendor request template
+├── types/
+│   └── template.types.ts           # Template type definitions
+├── components/

+├── RequestDetail.tsx               # Original component (backward compatible)
+└── RequestDetailTemplated.tsx      # New template-driven component
+```
+
+## Key Features
+
+### 1. **Template-Driven Configuration**
+- Define different views for different user types
+- Configure tabs, layout, and behavior via template
+- Automatic template selection based on request type and user role
+
+### 2. **Flexible Tab Management**
+- Dynamic tab visibility based on user permissions
+- Custom tab components for specialized workflows
+- Badge support for notifications (e.g., unread work notes)
+
+### 3. **Reusable Components**
+- Share common tabs across templates
+- Create custom tabs for specific use cases
+- Maintain consistency while allowing flexibility
+
+### 4. **Access Control**
+- Template-level access control
+- Tab-level visibility controls
+- Role-based feature access
+
+## Usage
+
+### Basic Usage
+
+```tsx
+import { RequestDetailTemplated } from '@/pages/RequestDetail/RequestDetailTemplated';
+
+// Automatic template selection
+<RequestDetailTemplated requestId="REQ-123" />
+
+// Explicit template selection
+<RequestDetailTemplated 
+  requestId="REQ-123" 
+  template="dealerClaim" 
+/>
+```
+
+### Creating a Custom Template
+
+```tsx
+// templates/myCustomTemplate.ts
+import { RequestDetailTemplate } from '../types/template.types';
+import { MyCustomTab } from '../components/tabs/MyCustomTab';
+
+export const myCustomTemplate: RequestDetailTemplate = {
+  id: 'myCustom',
+  name: 'My Custom Request',
+  description: 'Custom template for specialized workflows',
+
+  // Tab configuration
+  tabs: [
+    {
+      id: 'overview',
+      label: 'Overview',
+      icon: ClipboardList,
+      component: OverviewTab,
+      order: 1,
+    },
+    {
+      id: 'custom',
+      label: 'Custom Feature',
+      icon: Star,
+      component: MyCustomTab,
+      visible: (context) => context.user?.role === 'admin',
+      order: 2,
+    },
+  ],
+
+  defaultTab: 'overview',
+
+  // Header configuration
+  header: {
+    showBackButton: true,
+    showRefreshButton: true,
+    customActions: [],
+  },
+
+  // Quick actions configuration
+  quickActions: {
+    enabled: true,
+    customActions: [
+      {
+        id: 'my-action',
+        label: 'My Action',
+        icon: Zap,
+        action: async (context) => {
+          // Custom action logic
+        },
+        visible: (context) => true,
+        variant: 'default',
+      },
+    ],
+  },
+
+  // Layout configuration
+  layout: {
+    showQuickActionsSidebar: true,
+    fullWidthTabs: [],
+  },
+
+  // Access control
+  canAccess: (user, request) => {
+    return user?.role === 'admin';
+  },
+};
+```
+
+### Registering a Custom Template
+
+```tsx
+// templates/index.ts
+import { myCustomTemplate } from './myCustomTemplate';
+
+export const templateRegistry: TemplateRegistry = {
+  standard: standardTemplate,
+  dealerClaim: dealerClaimTemplate,
+  vendor: vendorTemplate,
+  myCustom: myCustomTemplate, // Add your custom template
+};
+
+// Update template selector
+export const selectTemplate: TemplateSelector = (user, request, routeParams) => {
+  if (request?.type === 'my-custom-type') {
+    return 'myCustom';
+  }
+  
+  // ... other logic
+  return 'standard';
+};
+```
+
+### Creating a Custom Tab Component
+
+```tsx
+// components/tabs/MyCustomTab.tsx
+import { TemplateContext } from '../../types/template.types';
+
+interface MyCustomTabProps extends Partial<TemplateContext> {}
+
+export function MyCustomTab({ request, user, refreshDetails }: MyCustomTabProps) {
+  return (
+    <div className="space-y-6">
+      <h2>My Custom Tab</h2>
+      <p>Request ID: {request?.requestId}</p>
+      <p>User: {user?.name}</p>
+      
+      <button onClick={refreshDetails}>
+        Refresh
+      </button>
+    </div>
+  );
+}
+```
+
+## Built-in Templates
+
+### 1. Standard Template
+**Use Case:** Default workflow requests
+
+**Features:**
+- Overview tab
+- Workflow visualization
+- Document management
+- Activity log
+- Work notes with real-time updates
+- Summary tab (for closed requests)
+
+**Access:** All users
+
+### 2. Dealer Claim Template
+**Use Case:** Dealer claim management with IO budget integration
+
+**Features:**
+- All standard features
+- **IO Tab** - Internal Order budget management
+  - Fetch available budget from SAP
+  - Block budget in SAP system
+  - View blocked IO details
+- Custom badges (claim status, priority)
+- E-Invoice generation (for completed claims)
+- Claim-specific workflows
+
+**Access:** Dealers, finance team, claim processors
+
+### 3. Vendor Template
+**Use Case:** Vendor purchase orders and invoices
+
+**Features:**
+- Overview tab
+- Workflow tracking
+- Document management
+- Activity log
+- Work notes
+- Shipment tracking (coming soon)
+
+**Access:** Vendors, procurement team
+
+## Template Context
+
+All tab components receive a `TemplateContext` object with:
+
+```tsx
+interface TemplateContext {
+  // Request data
+  request: any;
+  apiRequest?: any;
+  
+  // User info
+  user: any;
+  isInitiator: boolean;
+  isSpectator: boolean;
+  
+  // Workflow state
+  currentApprovalLevel: any;
+  isClosed: boolean;
+  needsClosure: boolean;
+  
+  // Actions
+  refreshDetails: () => Promise<void>;
+  onApprove: () => void;
+  onReject: () => void;
+  onPause: () => void;
+  onResume: () => void;
+  
+  // Additional context
+  unreadWorkNotes: number;
+  summaryDetails: any;
+  // ... and more
+}
+```
+
+## IO Tab - Dealer Claims
+
+The IO (Internal Order) tab enables SAP budget management for dealer claims:
+
+### Features
+
+1. **Budget Fetching**
+   - Enter IO number
+   - Fetch available budget from SAP
+   - Validate against claim amount
+
+2. **Budget Blocking**
+   - Block claim amount in SAP
+   - Generate SAP document number
+   - Track blocked amounts
+
+3. **Budget Release**
+   - Release blocked budget if needed
+   - Update SAP system
+
+### SAP Integration Points
+
+```tsx
+// TODO: Implement actual SAP integration
+const response = await fetch(`/api/sap/io/${ioNumber}/budget`);
+const data = await response.json();
+
+// Block budget
+const blockResponse = await fetch(`/api/sap/io/block`, {
+  method: 'POST',
+  body: JSON.stringify({
+    ioNumber,
+    amount: claimAmount,
+    requestId,
+  }),
+});
+```
+
+## Best Practices
+
+### 1. Template Design
+- Keep templates focused on specific use cases
+- Reuse common components when possible
+- Use visibility functions for conditional features
+
+### 2. Tab Components
+- Accept `TemplateContext` as props
+- Handle loading and error states
+- Use consistent UI patterns
+
+### 3. Access Control
+- Implement template-level access control
+- Use tab visibility for feature gating
+- Validate permissions server-side
+
+### 4. Performance
+- Use `useMemo` for expensive computations
+- Lazy load heavy components
+- Implement proper cleanup in lifecycle hooks
+
+## Migration Guide
+
+### From Original RequestDetail to Templated
+
+```tsx
+// Before
+import { RequestDetail } from '@/pages/RequestDetail/RequestDetail';
+<RequestDetail requestId="REQ-123" />
+
+// After (automatic template selection)
+import { RequestDetailTemplated } from '@/pages/RequestDetail/RequestDetailTemplated';
+<RequestDetailTemplated requestId="REQ-123" />
+
+// Or explicit template
+<RequestDetailTemplated 
+  requestId="REQ-123" 
+  template="dealerClaim" 
+/>
+```
+
+The original `RequestDetail` component remains available for backward compatibility.
+
+## Testing
+
+```tsx
+// Test template selection
+import { selectTemplate } from '@/pages/RequestDetail/templates';
+
+const template = selectTemplate(
+  { role: 'dealer' },
+  { category: 'claim-management' },
+  {}
+);
+
+expect(template).toBe('dealerClaim');
+
+// Test tab visibility
+const context: TemplateContext = {
+  user: { role: 'finance' },
+  isInitiator: false,
+  // ...
+};
+
+const ioTabVisible = dealerClaimTemplate.tabs
+  .find(tab => tab.id === 'io')
+  ?.visible?.(context);
+
+expect(ioTabVisible).toBe(true);
+```
+
+## Examples
+
+### Example 1: Add a New Tab to Existing Template
+
+```tsx
+// Register additional tab at runtime
+import { registerTemplate, dealerClaimTemplate } from '@/pages/RequestDetail/templates';
+import { InvoiceTab } from './components/tabs/InvoiceTab';
+
+const enhancedDealerTemplate = {
+  ...dealerClaimTemplate,
+  tabs: [
+    ...dealerClaimTemplate.tabs,
+    {
+      id: 'invoice',
+      label: 'E-Invoice',
+      icon: Receipt,
+      component: InvoiceTab,
+      visible: (context) => context.request?.status === 'completed',
+      order: 4,
+    },
+  ],
+};
+
+registerTemplate(enhancedDealerTemplate);
+```
+
+### Example 2: Custom Template Selector
+
+```tsx
+// Add custom logic to template selector
+export const selectTemplate: TemplateSelector = (user, request, routeParams) => {
+  // Route-based selection
+  if (routeParams?.template) {
+    return routeParams.template;
+  }
+  
+  // Request category
+  if (request?.category === 'claim-management') {
+    return 'dealerClaim';
+  }
+  
+  // User role
+  if (user?.role === 'vendor') {
+    return 'vendor';
+  }
+  
+  // Request metadata
+  if (request?.metadata?.templateId) {
+    return request.metadata.templateId;
+  }
+  
+  // Default
+  return 'standard';
+};
+```
+
+## Troubleshooting
+
+### Template Not Loading
+- Check template ID in registry
+- Verify template selector logic
+- Check console for errors
+
+### Tab Not Visible
+- Check `visible` function in tab config
+- Verify `TemplateContext` data
+- Check user permissions
+
+### Custom Tab Not Rendering
+- Ensure component accepts `TemplateContext` props
+- Check component imports
+- Verify tab order configuration
+
+## Future Enhancements
+
+- [ ] Template inheritance (extend base templates)
+- [ ] Dynamic tab loading (lazy load tabs)
+- [ ] Template versioning
+- [ ] Template analytics
+- [ ] Visual template builder
+- [ ] Template marketplace
