  The SAP error message /IWBEP/CM_MGW_RT058 Missing response data in changeset deferred processing mode typically occurs in the context of SAP Gateway services when there is an issue with the response data expected during a changeset operation. This error is often related to OData services and can arise in scenarios where multiple operations are being processed in a single request (changeset) but the expected response data is not being returned correctly.
  Cause:
  
  Missing Response Data: The error indicates that the system expected a response for one or more operations in the changeset, but it did not receive the necessary data.
  Deferred Processing: This error is specifically related to deferred processing mode, where the changeset is processed but the response is not returned immediately.
  Service Implementation Issues: There may be issues in the implementation of the OData service, such as missing or incorrect handling of the response for the operations defined in the changeset.
  Transaction Errors: If one of the operations in the changeset fails, it may lead to a situation where the expected response data is not generated.
  
  Solution:
  
  Check Service Implementation: Review the implementation of the OData service to ensure that all operations in the changeset are correctly handled and that appropriate response data is being returned.
  Debugging: Use debugging tools to trace the execution of the service and identify where the response data is missing. Check for any exceptions or errors that may be occurring during processing.
  Response Structure: Ensure that the response structure matches the expected format for the changeset. Each operation in the changeset should return a valid response.
  Error Handling: Implement proper error handling in the service to ensure that if one operation fails, it does not prevent the other operations from returning their responses.
  Testing: Test the changeset with different scenarios to ensure that all operations are functioning as expected and that the responses are being returned correctly.
  
  Related Information:
  
  SAP Gateway: Familiarize yourself with the SAP Gateway framework and how it handles OData services, especially in the context of changesets and deferred processing.
