PI Output: One Business System with multiple Channels

Hello,

I have a simple question which drives me crazy.

In our integration flow there is a interface split with two lanes behind. Each lane has a mapping and should have a unique channel to the business system.

So there are to cases. Either after the interface split the lane A will be chosen and the mapped data will be send over FTP to the business system A or lane B will be chosen and the mapped data will be send over SOAP to the business system A.

Input -> Interface splitt ->   lane A -> Mapping A -> FTP-Channel    -> BS1

                                      OR

                                        lane B -> Mapping A -> SOAP-Channel -> BS1

But I am not able to build the IF like that. I always endup with two lanes with mappings which are connected to the business system with a combined channel. And its not possible to give each lane/mapping an own/unique channel to talk to the business system.

Can some one tell me who I can solve this problem?

Greetings

Matthias
