• What is the cause and solution for SAP error message SADL_GW_MODEL004 - Do not use conversion exit &1 here. ?

  The SAP error message SADL_GW_MODEL004 with the description "Do not use conversion exit &1 here" typically occurs in the context of SAP Gateway and the SAP Data Access Layer (SADL). This error indicates that a conversion exit is being used in a context where it is not allowed, particularly when dealing with data models in the Gateway.
  Cause:
  The error is caused by the use of a conversion exit in a field that is being processed by the SAP Gateway. Conversion exits are used to format data for display or input, but they can interfere with the data handling in the Gateway, which expects raw data without any formatting. This is particularly relevant when defining data models or when using certain types of data binding in OData services.
  Solution:
  To resolve this error, you should:
  
  
  Identify the Field: Determine which field is causing the error. The error message will typically indicate the conversion exit that is being improperly used.
  
  
  Remove the Conversion Exit: Modify the data model or the relevant code to ensure that the conversion exit is not applied to the field in question. This may involve:
  
  Adjusting the data model definition to use the raw data type instead of the formatted type.
  Changing the way data is retrieved or processed in the OData service to avoid using conversion exits.
  
  
  
  Check Data Types: Ensure that the data types used in your data model are compatible with the expected input/output of the Gateway. Use standard data types that do not require conversion exits.
  
  
  Test the Changes: After making the necessary adjustments, test the OData service to ensure that the error is resolved and that the data is being processed correctly.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on SADL and OData services. This can provide insights into best practices for data modeling and handling.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and to share solutions.
  Debugging: Use debugging tools in SAP to trace the execution and identify where the conversion exit is being applied incorrectly.
  
  By following these steps, you should be able to resolve the SADL_GW_MODEL004 error and ensure that your OData service functions correctly without the interference of conversion exits.
