We're an ISV and currently we receive item master updates from SAP in the from of iDoc files of type EDI_DC40 (hope I got this right) delivered via FTP.
The client is now intent to deliver these same documents via SAP CPI to a web-api end-point on our side. While I understand the transport layer changes, unclear to me is if this will require changes to the code at our end that processes the iDoc currently.
I'd assume if the iDoc was transmitted as plain/text (utf8), the current code processing such files would work as is.
OTOH, if we received application/json or application/xml, it might be nearly as simple to reassemble the iDoc in its original form.
If neither of these two options are available, I need to find some documentation of what to expect so I can assess the effort to change the payload processor.
Any pointers in the right direction are greatly appreciated.
Many thanks,
Pete
