  The SAP error message /IWBEP/CM_CP100 Invalid OData version supplied typically occurs when there is a mismatch between the OData version expected by the SAP system and the version being used in the request. This error is related to the OData services in SAP Gateway and can arise in various scenarios, such as when consuming OData services from an external application or when testing services in the SAP Gateway Client.
  Cause:
  
  Incorrect OData Version: The client application or tool is sending a request with an OData version that is not supported by the SAP Gateway service.
  Service Configuration: The OData service may be configured to support a specific version, and the request does not match that version.

  Check OData Version: Ensure that the OData version specified in the request matches the version supported by the SAP Gateway service. Common versions are OData V2 and OData V4.

  Modify Client Request: If you are using a client application or tool, modify the request to specify the correct OData version in the headers.
  
  
  Review Service Metadata: Access the service metadata (usually available at the service URL with $metadata appended) to check which OData version is supported by the service.
  
  
  Update Service Configuration: If you have control over the OData service, ensure that it is configured to support the desired OData version. This may involve adjusting settings in the SAP Gateway service configuration.
