I've researching some info about -standard interfaces SAP-to-SAP connecting modules such as FI and SD through XI: http://help.sap.com/saphelp_erp2005/helpdata/en/42/cb899bfc0a136be10000000a1553f7/frameset.htm
These connections only mention a certain message interface "OUT" connected with an "IN" message with an proxy connection (type XI), it depends on the version but the "scenario" is always the same
I have a few questions about these interfaces:
1- Since this is ecc-to-ecc, do i need a Sender agreement? or is only Receiver det (from Business System to the same BS), interface det (without mapping) , receiver agreement (with channel xi),
I'm asking because there're interfaces inbound and outbound as well (sync or async) and i don't see any difference in the sap help
2- There's any way to test those scenarios (not sure how the interface works) ?
Any help would be appreciated,
