🚀 How to Use
For Dealers (Claim Management)
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
// Backend: Regular request
{
requestId: "REQ-2024-001",
category: "standard"
}
// Frontend: Same component
<RequestDetailTemplated requestId="REQ-2024-001" />
// Result: Shows standard tabs
Create Custom Template
// 1. Define template
export const myTemplate: RequestDetailTemplate = {
id: 'myCustom',
name: 'My Template',
tabs: [...],
// ... configuration
};
// 2. Register
import { registerTemplate } from '@/pages/RequestDetail/templates';
registerTemplate(myTemplate);
// 3. Use
<RequestDetailTemplated template="myCustom" requestId="REQ-123" />
