We have Proxy to SFTP Sceanrio. We are explicitly requesting for Transport Level Acknowledgement ( co_transport_acknowledgment) from ABAP Program. We are getting:
Ack in Success Scenario.
No Ack for System Error scenario. Ack is in waiting status
If the Error message is explicitly cancelled, we are getting Ack
We are expecting the error in acknowledgement when the status in PO is "System Error".
