• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED393 - Content-Disposition for non-stream property '&1' is not allowed ?

  The SAP error message /IWBEP/CM_V4_MED393 indicates that there is an issue with the Content-Disposition header for a non-stream property in an OData service. This typically occurs when the OData service is trying to return a property that is not a binary stream (like an image or file) but is being treated as if it were.
  Cause:
  The error is usually caused by one of the following:
  
  Incorrect Metadata Definition: The property in the OData model is defined as a stream or binary type, but the actual data being returned is not a stream.
  Service Implementation Issue: The implementation of the OData service may be incorrectly handling the property, leading to a mismatch between the expected and actual data types.
  Client Request: The client may be requesting the property in a way that implies it should be treated as a stream, even though it is not.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Metadata: Review the metadata definition of the OData service to ensure that the property in question is correctly defined. If it is a non-stream property, it should not be marked as a stream in the metadata.
  
  
  Adjust Service Implementation: If you are implementing the OData service, ensure that the property is being handled correctly in the service logic. If it is a non-stream property, make sure that it is not being treated as a stream in the response.
  
  
  Modify Client Request: If the error is triggered by a client request, check how the client is requesting the property. Ensure that the request does not imply that the property should be treated as a stream.
  
  
  Debugging: Use debugging tools to trace the request and response. This can help identify where the mismatch is occurring and provide insights into how to fix it.
