Dear Experts,
For building asynchronous interface in PI, I prefer to choose IDoc if 1 of the party is an SAP system.
For the other side of the party I've used FTP adapter to generate file which will be processed by PI into IDoc or vice versa.
I've got some input that asynchronous Web Service could be used to substitute the FTP adapter.
What do you think about this?
I think that by using FTP adapter, we have the physical file at the FTP folder so it would make the tracing from IDoc to file easier. In case we have to prove some questions from the client like "Where does this data come from?" we could give them the physical file as a prove that the data was sent from the other system. But with FTP, we have to manage the housekeeping since some old files might not be needed anymore and they need to be cleaned up before eating FTP server resources.
With web service, of course we don't need to do housekeeping which will make life easier, but then to make tracing easier, the other system has to make a log every time they send/receive any interface data.
Any input/thought would be appreciated.
Thank you,
Suwnadi C.
