• What is the cause and solution for SAP error message DT185 - Field &: User type & is generated proxy type, therefore not usable ?

  The SAP error message DT185 indicates that there is an issue with the data type being used in a proxy interface. Specifically, it states that the user type being referenced is a generated proxy type, which means it cannot be used in the context where it is being referenced.
  
  Cause:
  
  Generated Proxy Type: The error typically occurs when a generated proxy type (like a web service proxy) is being used in a context that expects a different type of data structure. This can happen if the proxy type is not properly defined or if there is a mismatch in the expected data types.
  Incorrect Mapping: If you are working with mappings in an integration scenario (like PI/PO), the mapping might be incorrectly set up to use a generated proxy type instead of a compatible type.
  Version Mismatch: There may be a version mismatch between the service definition and the proxy generated in the SAP
