• What is the cause and solution for SAP error message SADL_GW015 - Filter element '&1' is not among requested elements ?

  The SAP error message SADL_GW015 indicates that a filter element specified in a request is not included in the list of requested elements. This typically occurs in the context of SAP Gateway and the SAP ABAP programming model, particularly when using the SAP Data Access Layer (SADL) for OData services.
  Cause:
  The error is caused by a mismatch between the filter elements specified in the OData request and the elements that are actually requested in the service definition. This can happen due to:
  
  Incorrect Filter Specification: The filter element specified in the request does not exist in the data model or is misspelled.
  Service Definition Issues: The OData service may not have been properly defined to include the requested filter elements.
  Changes in Data Model: If the underlying data model has changed (e.g., fields were added or removed), the OData service may not reflect these changes.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the Filter Element: Verify that the filter element specified in the request is correct and exists in the data model. Ensure there are no typos or incorrect casing.
  
  
  Review OData Service Definition: Check the OData service definition in the SAP Gateway Service Builder (transaction code SEGW) to ensure that the filter element is included in the list of requested elements.
  
  
  Update the Service: If the filter element is missing from the service definition, you may need to update the service to include it. This can involve:
  
  Adding the missing field to the entity type in the service.
  Regenerating the service to ensure that the changes are reflected.
  
  
  
  Test the Service: After making changes, test the OData service again to ensure that the error is resolved.
  
  
  Check for Caching Issues: Sometimes, caching can cause issues. Clear the cache for the OData service or restart the relevant services if necessary.
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SEGW (Service Builder) to manage OData services and SE80 (Object Navigator) to check the underlying data model.
  SAP Notes: Check for any relevant SAP Notes that might address known issues related to this error message.
  Debugging: If you have access, you can debug the OData service to see the exact request being processed and identify where the mismatch occurs.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
