Our company using SFTP method to drop xml file into another service provider server/folder. off late , service provider says, they have not received the file but our Process Integration system (of SAP PI), shows, "Delivered" message and PI team believes when there is a "Delivered" message it is successful, but service provider did not receive. Is this still a good technology ? or is there any acknowledgement process can be implemented in this?
Our operating system is Windows.
