Now we encountered a scenario:
SAP R/3 send out a multiple rows message, one row is for one plant. for example, there are three rows in this message, two rows for plant A, one row for plant B.
then we need split this message into several messages, each message should only contain rows for one plant. then send each message to different plant according to plantID.
we don't want to use BPM, multiple message mapping seems a good solution, but it seems multiple message mapping can only send all splited messages to one business system.
