• What is the cause and solution for SAP error message SRF_AUTHORING247 - Export parameter of Structure/Table not supported, other than predefined ?

  The SAP error message SRF_AUTHORING247, which states "Export parameter of Structure/Table not supported, other than predefined," typically occurs when you are trying to use a structure or table as an export parameter in a function module or method that does not support it. This is a common issue when working with SAP's Service Runtime Framework (SRF) or when creating service definitions in SAP Gateway.
  Cause:
  
  Unsupported Data Types: The error arises because the function module or method you are trying to use does not allow structures or tables as export parameters. Only predefined types (like simple data types) are allowed.
  Service Definition Issues: If you are defining a service in SAP Gateway and trying to expose a function module that has a structure or table as an export parameter, it will lead to this error.
  Incompatibility with OData: When creating OData services, the underlying function modules or methods must adhere to specific data type restrictions, and complex types (like structures or tables) are often not supported as export parameters.
  
  Solution:
  
  Change Export Parameters: Modify the function module or method to use simple data types (like CHAR, INT, etc.) as export parameters instead of structures or tables.
  Use Import Parameters: If you need to pass complex data, consider using import parameters instead of export parameters. You can pass the structure or table as an import parameter and return the results as simple data types.
  Refactor the Logic: If the logic requires returning multiple values, consider returning a single structure that contains all the necessary fields as a single export parameter, if the framework allows it.
  Check Service Definition: Review the service definition in the SAP Gateway and ensure that the function module or method adheres to the expected data types for OData services.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidelines on creating function modules and methods that are compatible with OData services.
  SAP Community: Engage with the SAP Community forums to find discussions and solutions related to similar issues.
  Debugging: Use transaction codes like SE37 (Function Builder) or SE80 (Object Navigator) to debug the function module and check the parameter types.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  
  By following these steps, you should be able to resolve the SRF_AUTHORING247 error and successfully implement your desired functionality in SAP.
