• What is the cause and solution for SAP error message /IWFND/MED193 - Conversion binding for structure '&1' not allowed. ?

  The SAP error message /IWFND/MED193 Conversion binding for structure '&1' not allowed typically occurs in the context of SAP Gateway and OData services. This error indicates that there is an issue with the data binding for a structure in the OData service, specifically that the conversion binding for the specified structure is not permitted.
  Cause:
  
  Unsupported Structure: The structure you are trying to bind may not be supported for conversion in the context of the OData service.
  Incorrect Data Model: The data model defined in the OData service may not align with the structure you are trying to use.
  Incompatible Data Types: There may be incompatible data types in the structure that prevent proper conversion.
  Service Configuration Issues: The OData service may not be configured correctly to handle the specified structure.
  
  Solution:
  
  Check Structure Definition: Review the structure definition in the ABAP Dictionary (SE11) to ensure it is correctly defined and does not contain unsupported data types.
  Modify OData Model: If the structure is not supported, consider modifying the OData model to use a different structure or entity type that is compatible.
  Adjust Data Types: Ensure that the data types used in the structure are compatible with OData standards. For example, avoid using complex types that cannot be serialized properly.
  Service Implementation: If you are implementing a custom OData service, ensure that the implementation correctly handles the conversion of the structure.
  Regenerate Service: If changes have been made to the structure or the OData model, regenerate the OData service and re-activate it.
  Check Service Metadata: Use the service metadata (e.g., by accessing the service URL with $metadata) to verify that the structure is correctly exposed in the OData service.
