• What is the cause and solution for SAP error message /IWBEP/CM_V4_APPS070 - Unsupported content type '&1' for stream property '&2' ?

  The SAP error message /IWBEP/CM_V4_APPS070 Unsupported content type '&1' for stream property '&2' typically occurs in the context of SAP Gateway and OData services. This error indicates that the content type being sent in the request does not match the expected content type for the specified stream property.
  Cause:
  
  
  Incorrect Content Type: The client is sending a request with a content type that is not supported by the OData service for the specified stream property. For example, if the service expects a binary stream (like application/octet-stream) but receives a different type (like application/json), this error will occur.
  
  
  Configuration Issues: There may be misconfigurations in the OData service or the way the stream property is defined in the metadata.
  
  
  Client-Side Issues: The client application (e.g., a UI5 application or another consumer of the OData service) may not be correctly setting the content type in the request headers.
  
  
  Solution:
  
  
  Check Content Type: Ensure that the client application is sending the correct content type in the request. For binary data, it should typically be application/octet-stream. For other types of data, refer to the OData service documentation to confirm the expected content type.
  
  
  Review OData Service Metadata: Check the metadata of the OData service to understand the expected content types for the stream properties. You can access the metadata by appending $metadata to the service URL.
  
  
  Adjust Client Code: If you are developing a client application, make sure that the code responsible for making the OData requests is correctly setting the content type based on the type of data being sent.
  
  
  Test with Tools: Use tools like Postman or SAP Gateway Client to manually test the OData service with the correct content type to ensure that the service is functioning as expected.
  
  
  Debugging: If the issue persists, consider enabling debugging in the SAP Gateway to get more detailed logs about the request and response, which can help identify the root cause.
