• What is the cause and solution for SAP error message /IWPGW/TGW_TCM_MSG016 - Filter property &1 on entity &2 not supported ?

  The SAP error message /IWPGW/TGW_TCM_MSG016 indicates that a filter property specified in a request for an OData service is not supported for the specified entity. This typically occurs when the OData service is trying to apply a filter on a property that is either not defined for the entity or is not supported for filtering in the context of the OData service.
  Cause:
  
  Unsupported Property: The property you are trying to filter on may not be part of the entity's metadata or is not marked as filterable.
  Incorrect Property Name: There might be a typo or incorrect property name in the filter query.
  Entity Configuration: The entity might not be configured to allow filtering on certain properties due to business logic or design decisions.
  Versioning Issues: If the OData service has been updated or changed, the property may have been removed or altered.
  
  Solution:
  
  Check Metadata: Review the OData service metadata (usually accessible via a $metadata endpoint) to confirm that the property you are trying to filter on exists and is marked as filterable.
  Correct Property Name: Ensure that the property name in your filter query matches exactly with the name defined in the metadata, including case sensitivity.
  Review Service Implementation: If you have access to the backend implementation, check the service logic to see if the property is intentionally excluded from filtering.
  Consult Documentation: Refer to the documentation for the specific OData service to understand which properties are supported for filtering.
  Contact Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP team for assistance.
