• What is the cause and solution for SAP error message /IWFND/CM_MGW_EDP102 - Execution mode &1 is invalid for Entity GetStream operation ?

  The SAP error message /IWFND/CM_MGW_EDP102 Execution mode &1 is invalid for Entity GetStream operation typically occurs in the context of SAP Gateway and OData services when there is an issue with the execution mode specified for an operation that retrieves a stream (binary data) from an entity.
  Cause:
  
  Invalid Execution Mode: The error indicates that the execution mode specified (represented by &1 in the message) is not valid for the GetStream operation. The execution mode could be set to a value that is not supported for streaming operations.
  Configuration Issues: There may be misconfigurations in the OData service or the underlying data model that lead to this error.
  Service Implementation: The implementation of the OData service might not correctly handle the GetStream operation, leading to an invalid execution mode being used.
  
  Solution:
  
  
  Check Execution Mode: Review the execution mode being used in the OData service implementation. Ensure that it is set to a valid value for the GetStream operation. Common execution modes include READ, CREATE, UPDATE, and DELETE, but for streaming, you may need to ensure that the mode is appropriate for binary data retrieval.
  
  
  Service Configuration: Verify the configuration of the OData service in the SAP Gateway. Ensure that the service is correctly defined to handle streaming operations. This includes checking the service metadata and ensuring that the entity set is properly configured to support binary data.
  
  
  Review Implementation: If you have custom logic in your OData service implementation, review the code to ensure that it correctly handles the GetStream operation. Make sure that the logic does not inadvertently set an invalid execution mode.
  
  
  Check for Updates: Ensure that your SAP system is up to date with the latest support packages and notes, as there may be fixes or improvements related to OData services and streaming operations.
  
  
  Debugging: If the issue persists, consider debugging the OData service to trace the execution flow and identify where the invalid execution mode is being set or used.
