• What is the cause and solution for SAP error message /IWBEP/SBOD147 - Function Import '&1': No return is currently not supported by the runtime ?

  The SAP error message /IWBEP/SBOD147 Function Import '&1': No return is currently not supported by the runtime typically occurs in the context of SAP Gateway and OData services when a function import is defined without a return type. This can happen when you are trying to execute a function import that is expected to return data, but the function is defined in such a way that it does not return any data.
  Cause:
  
  Function Import Definition: The function import in the OData service is defined without a return type. In OData, function imports should either return a single entity, a collection of entities, or a complex type.
  Service Implementation: The implementation of the function import in the backend (ABAP) does not return any data, which is not supported by the OData runtime.
  Service Metadata: The service metadata might not be correctly defined, leading to the runtime not recognizing the expected return type.
  
  Solution:
  
  
  Check Function Import Definition:
  
  Go to the OData service definition in the SAP Gateway Service Builder (transaction code SEGW).
  Ensure that the function import is defined with a proper return type. If it is meant to return data, specify the appropriate entity type or complex type.
  
  
  
  Modify the Implementation:
  
  If the function import is intended to perform an action without returning data, consider changing its definition to a Action instead of a Function Import. Actions in OData are meant for operations that do not return data.
  If it should return data, ensure that the ABAP implementation of the function import includes a return statement that returns the expected data.
  
  
  
  Regenerate the Service:
  
  After making changes to the function import definition or implementation, regenerate the service in the Service Builder and activate it.
  Test the service again to see if the error persists.
  
  
  
  Check Service Metadata:
  
  Use the /IWBEP/REG_SERVICE transaction to check the service metadata and ensure that the function import is correctly defined with the expected return type.
  
  
  
  Related Information:
  
  OData Protocol: Understanding the OData protocol and how function imports and actions are defined can help in troubleshooting similar issues.
  SAP Gateway: Familiarity with SAP Gateway and its components, including the Service Builder and the backend implementation, is essential for resolving such errors.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues related to your version of SAP Gateway or OData services.
  
  By following these steps, you should be able to resolve the error and ensure that your OData service functions as expected.
