Mapping to several receivers

Hi.

I got a file X into XI (JDBC).

This file shall I map in to file Y (iDoc into SAP) and part of file X shall I map to file Z (FTP out to an server).

Y and Z are going to different receivers.

I use several(4) mappingprograms to create Y and Z.

Can I use the same Interface Mapping for all mappingprograms?

File X to Y is working in the IB Configuration but how can I set up the IB Configuration to send file Z.

Will be very happy if someone can help me.

Thanks.
