RFC as MultiMessage with envelope Messages/Message1/.. ?

Dear all,

I received a RFC from SAP system. In my mapping I would like to do

a message split and set the occurence of target message to 0...unbounded.

The RFC get the envelope Messages/Message1 automatically.

I tested the mapping in repository and it works. But when sending a

RFC the adapter does not wrap the message with this envelope.

What to do?

Thanks

Chris
