Issue in sending EDI Invoice to multiple partners from e.g customer and broker BP and ES

We need to send Billing output with medium 6 EDi to multiple partners like customer and broker.

After maintaining condition record customer it is getting trigerred automatically at billing level.

But same is not happening for Broker partner function ES.

As ES is vendor we already have LIFNR added in field catalog for o/p billing and created table and access sequence as well still it is not getting determined...

Please suggest.
