• What is the cause and solution for SAP error message /IWFND/CM_MGW_EDP081 - -- Deep Create Entity Section -- ?

  The SAP error message /IWFND/CM_MGW_EDP081 typically occurs in the context of OData services when there is an issue with the deep create operation. This error is related to the Entity Data Model (EDM) and indicates that there is a problem with the data being sent to the service for creating an entity that has related entities (deep create).
  Cause:
  
  Invalid Data Structure: The data being sent in the request may not match the expected structure defined in the OData service. This can happen if the payload is missing required fields or has incorrect data types.
  Navigation Properties: If the entity being created has navigation properties (relationships to other entities), the related entities must also be correctly structured and included in the request.
  Authorization Issues: The user may not have the necessary permissions to create the entity or its related entities.
  Service Configuration: There may be issues with the OData service configuration, such as missing or incorrectly defined associations between entities.
  Backend Logic: There could be issues in the backend logic (e.g., BAPIs, function modules) that handle the creation of the entity.
  
  Solution:
  
  Check Payload Structure: Review the JSON or XML payload being sent to the OData service. Ensure that it matches the expected structure defined in the service metadata.
  Validate Required Fields: Make sure all required fields for the main entity and any related entities are included in the request.
  Review Navigation Properties: If the entity has navigation properties, ensure that the related entities are correctly included in the payload.
  Authorization Check: Verify that the user has the necessary authorizations to perform the create operation on the entity and its related entities.
  Debugging: Use transaction codes like /IWFND/ERROR_LOG to check for detailed error logs that can provide more context on the issue.
  Service Implementation: If you have access to the backend implementation, check the logic for creating the entity and ensure it handles deep creates correctly.
  Test with Simplified Payload: If possible, test the service with a simplified payload that only includes the main entity without related entities to isolate the issue.
