• What is the cause and solution for SAP error message /IWBEP/CM_CP020 - Proxy model error: Edm.Stream is not supported in V2 ?

  The SAP error message /IWBEP/CM_CP020 Proxy model error: Edm.Stream is not supported in V2 typically occurs in the context of SAP Gateway and OData services when there is an attempt to use a data type that is not supported in the version of the OData service being used. Specifically, Edm.Stream refers to a binary stream data type, which is often used for handling file uploads or downloads.
  Cause:
  
  Unsupported Data Type: The error indicates that the OData service is trying to use the Edm.Stream type, which is not supported in OData V2. This can happen if the service is defined to use V2 but is trying to handle binary data.
  Service Configuration: The OData service might be incorrectly configured to handle binary data, or the model might not be set up to support streaming.
  Version Mismatch: There may be a mismatch between the client and server versions of the OData service, where the client is expecting a newer version that supports Edm.Stream.
  
  Solution:
  
  Check OData Version: Ensure that the OData service is using a version that supports Edm.Stream. If you need to handle binary data, consider upgrading to OData V4, which supports this data type.
  Modify Service Definition: If upgrading is not an option, you may need to modify the service definition to avoid using Edm.Stream. Instead, consider using base64 encoding for binary data or other supported data types.
  Update Client Code: If you are consuming the OData service, ensure that your client code is compatible with the service version. If the service is V2, avoid using features that are only available in V4.
  Check Model Configuration: Review the model configuration in the SAP Gateway to ensure that it is set up correctly to handle the data types you are working with.
  
  Related Information:
  
  OData Versions: Familiarize yourself with the differences between OData V2 and V4, especially regarding data types and capabilities.
  SAP Gateway Documentation: Refer to the official SAP Gateway documentation for guidance on configuring OData services and handling binary data.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other users who may have encountered similar issues.
