• What is the cause and solution for SAP error message /IWBEP/SBOD160 - Function Import '&1': No return type expected (check Return Type Kind) ?

  The SAP error message /IWBEP/SBOD160 Function Import '&1': No return type expected (check Return Type Kind) typically occurs in the context of SAP Gateway and OData services when there is a mismatch in the expected return type of a function import in an OData service.
  Cause:
  This error indicates that the function import defined in the OData service is not configured correctly regarding its return type. Specifically, it suggests that the function import is expected to return a certain type of data, but the configuration does not align with that expectation. Common causes include:
  
  Incorrect Return Type Configuration: The function import may be defined without a return type when one is expected, or it may be defined with a return type that is not appropriate for the function's logic.
  Service Definition Issues: The OData service definition might not be properly set up, leading to inconsistencies in how the function import is interpreted.
  Model Issues: The underlying data model may not be correctly defined, leading to issues with how the function import is expected to behave.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Function Import Definition:
  
  Go to the SAP Gateway Service Builder (transaction code SEGW).
  Locate the function import that is causing the issue.
  Ensure that the return type is correctly defined. If the function is not supposed to return any data, it should be marked as a void return type.
  
  
  
  Adjust Return Type:
  
  If the function import is supposed to return data, ensure that the return type is set correctly in the service definition.
  If it is not supposed to return any data, ensure that it is defined as such in the service metadata.
  
  
  
  Regenerate the Service:
  
  After making changes to the function import definition, regenerate the service by right-clicking on the project and selecting "Generate" or "Regenerate".
  Activate the service and check if the error persists.
  
  
  
  Check Service Metadata:
  
  Use the /IWBEP/IF_MPC interface to check the metadata of the service and ensure that the function import is correctly defined in the metadata.
  
  
  
  Test the Service:
  
  After making the necessary adjustments, test the OData service using the SAP Gateway Client (transaction code /IWFND/GW_CLIENT) to ensure that the function import works as expected.
