• What is the cause and solution for SAP error message /IWBEP/CM_CP045 - Filter already set on request ?

  The SAP error message /IWBEP/CM_CP045 Filter already set on request typically occurs in the context of SAP Gateway and OData services. This error indicates that a filter has already been applied to the request, and the system is not allowing multiple filters to be set on the same request.
  Cause:
  
  Multiple Filters: The error is often triggered when a request attempts to apply more than one filter on the same entity set or resource.
  Incorrect OData Query: The OData query might be incorrectly formed, leading to the application of multiple filters unintentionally.
  Service Implementation: The implementation of the OData service might not be handling the filters correctly, leading to conflicts.
  
  Solution:
  
  
  Review the OData Request: Check the OData request being sent to the service. Ensure that only one filter is being applied at a time. If multiple filters are needed, consider combining them into a single filter expression.
  
  
  Modify the Service Implementation: If you have control over the OData service implementation, review the code to ensure that it correctly handles filter parameters. You may need to adjust the logic to allow for multiple filters or to handle them in a way that avoids conflicts.
  
  
  Use Query Options Correctly: Make sure that you are using the OData query options correctly. For example, if you are using $filter, ensure that it is formatted properly and does not conflict with other query options.
  
  
  Debugging: If you have access to the backend, you can debug the OData service to see how the filters are being processed. This can help identify where the conflict is occurring.
  
  
  Check for Known Issues: Sometimes, specific versions of SAP Gateway or OData services may have known issues. Check SAP Notes or the SAP Community for any related issues and patches.
