  The SAP error message /IWBEP/MC_SB_DPC_ADM020 indicates that a specified filter parameter is not recognized as part of the data model in the context of an OData service. This typically occurs when a client application (like an SAP Fiori app) tries to query an OData service with a filter parameter that is not defined in the service's metadata.
  Cause:
  
  Incorrect Filter Parameter: The filter parameter specified in the OData request does not match any of the fields defined in the OData service's metadata.
  Model Changes: The underlying data model may have changed, and the filter parameter was removed or renamed.
  Typographical Errors: There may be a typo in the filter parameter name in the request.
  Service Versioning: If the OData service has multiple versions, the filter parameter may exist in one version but not in another.
  
  Solution:
  
  Check Metadata: Review the OData service's metadata (usually accessible via the $metadata endpoint) to confirm the available filter parameters. Ensure that the parameter you are trying to use is defined in the model.
  Correct the Request: If there is a typo or incorrect parameter, correct the request to use the appropriate filter parameter as defined in the metadata.
  Update Client Application: If the client application is using an outdated version of the OData service, update it to use the latest version that includes the correct filter parameters.
  Consult Documentation: Refer to the documentation for the OData service to understand the expected parameters and their correct usage.
  Debugging: If you have access to the backend, you can debug the OData service to see how it processes the incoming request and identify where the mismatch occurs.
  
  Related Information:
