• What is the cause and solution for SAP error message /IWBEP/CM_V4_RUNTIME061 - Return of action '&1' to be expected void ?

  The SAP error message /IWBEP/CM_V4_RUNTIME061 Return of action '&1' to be expected void typically occurs in the context of SAP Gateway and OData services. This error indicates that an action defined in your OData service is expected to return no data (void), but it is returning some data instead.
  Cause:
  
  Action Definition: The action is defined in the OData service metadata as a void action, meaning it should not return any data.
  Implementation Issue: The implementation of the action in the backend (ABAP code) is returning a value or a structure instead of returning nothing.
  Service Configuration: There might be a mismatch between the service definition and the actual implementation.
  
  Solution:
  
  Check Action Definition: Review the OData service metadata (service document) to ensure that the action is indeed defined as a void action.
  Review Implementation: 
  
  Go to the ABAP implementation of the action and ensure that it does not return any data. If it is returning a value, modify the code to ensure it returns nothing (e.g., use RETURN without any value).
  If the action is supposed to perform some operations without returning data, ensure that the return statement is correctly implemented.
  
  
  Regenerate Service: After making changes, regenerate the OData service and re-test to ensure that the error is resolved.
  Check Service Binding: Ensure that the service is correctly bound and activated in the SAP Gateway.
  
  Related Information:
  
  OData Actions: In OData, actions are operations that can be invoked on entities. They can be defined to return data or to be void.
