Connecting of an external system by IDOC adapter


Hello everybody,

we want to connect an external (storage) system to XI by IDOC-Adapter.

In a scenario without XI the R/3 backend triggers the external system by RFC-Call (TCPIP-conncetion) and an program on the external system is called. This program executes an RFC-call on the R/3 to get the IDOC-informations.

IN the new scenario (with XI) the R/3 Backend sends the IDOC information to XI. The XI routes this to external system. An TCPIP-Connection is needed which calls the program from the external system.

But how should this work? The program can not (or should not) call the R/3 Backend directly but the XI.

What has to be done now? Has the program of the external system changed so that it can understand IDOC-structure directly?

Or do I have to implement a business process scenario to guarantee that the external system reads the IDOC data in XI (similar to "old" scenario?

Thanks a lot!
