• 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 system.
  
  Solution:
  
  
  Check Proxy Generation: Ensure that the proxy has been generated correctly. You may need to regenerate the proxy to ensure it is up to date with the service definition.
  
  Use transaction SPROXY to check the proxy and regenerate it if necessary.
  
  
  
  Review Data Types: Verify that the data types being used in your mappings or function calls are compatible with the expected types. If you are using a generated proxy type, ensure that it is being used in the correct context.
  
  
  Adjust Mappings: If you are using SAP PI/PO, check the mappings in your integration scenario. Make sure that the source and target types are compatible and that you are not trying to map a generated proxy type to a non-compatible type.
  
  
  Check Service Definition: Ensure that the service definition (WSDL) is correctly defined and that the proxy is generated based on the latest version of the service definition.
  
  
  Consult Documentation: If the issue persists, consult the SAP documentation or support for specific guidance related to the version of SAP you are using.
