FILE to multiple BAPI/RFC calls

Hi,

I have one input source (CSV with about 100 rows) and I wish to call a custom rfc for each row in my spreadsheet. (The custom RFC has a single flat import structure as opposed to a table or anything complex).

I am struggling to do this in XI.

I assumed I needed to assign one source to multiple targets in the Message interfaces, but this errors on activation due to the RFC occurrence being set to 1.

Do I need to do the same trick as with IDOCS or am I missing the point somewhere?

I have read several threads and one in particular seems to indicate it is possible, but so far this has evaded me.

Please could you point me in the right direction.

Thanks

Andrew
