Mapping: Problem with duplicating Subtrees
i've got a Problem in message mapping, as I try to duplicate a subtree of an IDoc (= target structure).
In some mappings i can do it without problems, and the mapping is working correct.
In other mappings i can duplicate them indeed, but if I save the mapping, all the subtrees (and the corresponding target field mappings) are removed automatically.
Can someone tell me why this happens and how i can solve this problem?
Thank you in advance,
