• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED373 - Collection for Edm.Stream property '&INTERNAL_NAME' not allowed ?

  The SAP error message /IWBEP/CM_V4_MED373 indicates that there is an issue with the handling of an Edm.Stream property in an OData service. This error typically arises when there is an attempt to access or manipulate a property that is defined as a stream (binary data) in the OData model, but the operation being performed is not allowed for that property.
  Cause:
  
  
  Incorrect Property Type: The property in question (&INTERNAL_NAME) is defined as an Edm.Stream, which is meant for binary data (like files or images). If you are trying to perform operations that are not compatible with stream properties (like certain types of queries or updates), this error can occur.
  
  
  Service Configuration: The OData service may not be properly configured to handle stream properties. This could be due to missing configurations in the service definition or issues in the underlying data model.
  
  
  Client-Side Issues: If the client application is trying to access or manipulate the stream property incorrectly (e.g., using the wrong HTTP method), this error can also be triggered.
  
  
  Solution:
  
  
  Check Property Definition: Ensure that the property &INTERNAL_NAME is correctly defined as an Edm.Stream in your OData service metadata. Verify that the data type and attributes are set correctly.
  
  
  Review OData Operations: Make sure that the operations you are trying to perform on the stream property are valid. For example, if you are trying to retrieve or update the stream, ensure you are using the correct HTTP methods (GET for retrieval, PUT/PATCH for updates).
  
  
  Service Configuration: Review the OData service configuration to ensure that it supports stream properties. This may involve checking the service implementation in the backend (e.g., ABAP code) to ensure that it correctly handles stream data.
  
  
  Client-Side Code: If you are using a client application (like SAP Fiori or a custom application), check the code that interacts with the OData service. Ensure that it is correctly handling the stream property according to the OData protocol.
  
  
  Testing with Tools: Use tools like Postman or SAP Gateway Client to test the OData service directly. This can help isolate whether the issue is with the service itself or with the client application.
  
  
  Related Information:
  
  OData Documentation: Review the OData documentation for details on how to work with Edm.Stream properties, including the correct usage patterns and limitations.
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific version of the OData service you are using.
  Debugging: If you have access to the backend system, consider debugging the OData service to trace the request and identify where the error is occurring.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
