+# Dealer Claim Financial Settlement Workflow
+
+This document outlines the workflow for financial settlement of dealer claims within the Royal Enfield platform, following the transition from direct DMS integration to an Azure File Storage (AFS) based data exchange with SAP.
+
+## Workflow Overview
+
+The financial settlement process ensures that dealer claims are legally documented and financially settled through Royal Enfield's SAP system.
+
+### 1. Legal Compliance: PWC E-Invoicing
+Once the **Dealer Completion Documents** are submitted and approved by the **Initiator (Requestor Evaluation)**, the system triggers the legal compliance step.
+
+- **Service**: `PWCIntegrationService`
+- **Action**: Generates a signed E-Invoice via PWC API.
+- **Output**: IRN (Invoice Reference Number), Ack No, Ack Date, Signed Invoice (PDF/B64), and QR Code.
+- **Purpose**: Ensures the claim is legally recognized under GST regulations.
+
+### 2. Financial Posting: AFS/CSV Integration
+The financial settlement is handled by exchanging data files with SAP via **Azure File Storage (AFS)**.
+
+- **Action**: The system generates a **CSV file** containing the following details:
+    - Invoice Number (from PWC)
+    - Invoice Amount (with/without GST as per activity type)
+    - GL Code (Resolved based on Activity Type/IO)
+    - Internal Order (IO) Number
+    - Dealer Code
+- **Storage**: CSV is uploaded to a designated folder in AFS.
+- **SAP Role**: SAP periodically polls AFS, picks up the CSV, and posts the transaction internally.
+
+### 3. Payment Outcome: Credit Note
+The result of the financial posting in SAP is a **Credit Note**.
+
+- **Workflow**:
+    - SAP generates a Credit Note and uploads it back to AFS.
+    - RE Backend monitors the AFS folder.
+    - Once a Credit Note is detected, the system retrieves it and attaches it to the workflow request.
+    - An email notification (using `creditNoteSent.template.ts`) is sent to the dealer.
+
+## Sequence Diagram
+
+```mermaid
+sequenceDiagram
+    participant Dealer
+    participant Backend
+    participant PWC
+    participant AFS as Azure File Storage
+    participant SAP

+    SAP->>SAP: Post Financials
+    SAP->>AFS: Upload Credit Note
+    Backend->>AFS: Poll/Retrieve Credit Note
+    Backend->>Dealer: Send Credit Note Notification
+```
+
+## GL Code Resolution
+The GL Code is solved dynamically based on:
+1.  **Activity Type**: Each activity (e.g., Marketing Event, Demo) has a primary GL mapping.
+2.  **Internal Order (IO)**: If specific IO logic is required, the GL can be overridden.
+
+## Summary of Integration Points
+| Component | Integration Type | Responsibility |
+| :--- | :--- | :--- |
+| **PWC** | REST API | Legal E-Invoice |
+| **AFS (Azure)** | File Storage SDK | CSV Exchange |
+| **SAP** | Batch Processing | Financial Posting & Credit Note |
