Implementation Description - Configurable Return Processing

Summary

This PR introduces a shop-level configuration to determine whether Shopify returns are processed as Credit Memos or Return Orders in Business Central. The implementation uses an interface-based strategy pattern for extensibility, updates UI labels for clarity, and includes test coverage for Return Order creation.

Changes

New Functionality:

1. Shop-Level Configuration:

   • Added "Process Returns As" field to Shpfy Shop table (field 136, enum type).
   • Added corresponding field to Shpfy Shop Card page.

2. Strategy Pattern Implementation:

   • Created Shpfy IProcess Returns As interface with GetTargetDocumentType() method.
   • Created Shpfy Process Returns As enum (ID 30180) implementing the interface.
   • Enum values:
     • Credit Memo (value 0): Implementation = Shpfy Process Credit Memo codeunit
     • Return Order (value 1): Implementation = Shpfy Process Return Order codeunit

3. Implementation Codeunits:

   • Shpfy Process Credit Memo (ID 30236): Returns Sales Document Type::"Credit Memo".
   • Shpfy Process Return Order (ID 30422): Returns Sales Document Type::"Return Order".

4. Refund Processing Logic Update:

   • Modified ShpfyRetRefProcCrMemo codeunit CreateSalesDocument procedure.
   • Retrieves the shop configuration and uses the interface to determine the document type.

5. UI Updates for Clarity:

   • Shpfy Refund Page: Changed action caption from "Create Credit Memo" to "Create Sales Document".
   • Shpfy Refunds Page: Changed action caption from "Create Credit Memo" to "Create Sales Document".
   • Changed the action image from CreateCreditMemo to CreateDocument.
   • Updated Enum caption: "Auto Create Credit Memo" → "Auto Create Sales Document".

Architecture Benefits:

• Extensibility: Interface-based design allows partners to add custom document types.
• Flexibility: Shop-level configuration provides per-shop control over return handling.
• Clarity: UI updates make it clear that document type varies based on configuration.
• Maintainability: Strategy pattern centralizes document type logic.

Prerequisites:

• Shopify Connector must be configured with valid shop credentials.
• Shop setting "Process Returns As" determines the document type for all returns in that shop.
• BC number series for both Credit Memos and Return Orders should be configured.

Tests

Modified ShpfyOrderRefundTest codeunit with enhanced coverage:

1. Code Quality Improvements:

   • Fixed typo: ResetProccesOnRefund → ResetProcessOnRefund (4 occurrences).

2. New Test: Return Order Creation:

   • UnitTestCreateReturnOrder(): Validates Return Order creation from Shopify refund.
   • Configures shop with Process Returns As = "Return Order".
   • Verifies SalesHeader."Document Type" = "Return Order".
   • Ensures interface-based routing works correctly.
