• What is the cause and solution for SAP error message /IWBEP/SBDSP_DM037 - In Delete operations only Input mapping direction is allowed ?

  The SAP error message /IWBEP/SBDSP_DM037 typically occurs in the context of OData services when there is an issue with the mapping direction of the input parameters during a delete operation. This error indicates that only input mapping direction is allowed for delete operations, which means that the system expects certain parameters to be defined in a specific way.
  Cause:
  The error is caused by an incorrect configuration of the OData service, particularly in the mapping of the entity types and their properties. In delete operations, the OData service expects the input parameters to be mapped correctly, and if there are any output parameters or incorrect mapping directions defined, this error will be triggered.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the OData Service Definition:
  
  Go to the OData service definition in the SAP Gateway Service Builder (transaction code SEGW).
  Ensure that the entity set you are trying to delete is correctly defined and that the delete operation is properly configured.
  
  
  
  Review the Mapping:
  
  In the Service Builder, check the mapping for the delete operation. Make sure that only input parameters are defined for the delete operation and that there are no output parameters.
  Ensure that the mapping direction for the delete operation is set to "Input" only.
  
  
  
  Adjust the Data Model:
  
  If you have custom logic or additional parameters in your delete operation, review them to ensure they comply with the expected input mapping direction.
  Remove any unnecessary output parameters or adjust the mapping to ensure it aligns with the delete operation requirements.
  
  
  
  Regenerate the Service:
  
  After making the necessary changes, regenerate the OData service to apply the updates.
  You can do this by right-clicking on the service in the Service Builder and selecting "Regenerate".
  
  
  
  Test the Service:
  
  After regeneration, test the delete operation again to see if the error persists. Use tools like Postman or the SAP Gateway Client (transaction code /IWFND/GW_CLIENT) to perform the delete operation.
