Mutliple receivers

Hi All,

I got 2 queries.

1.Can anyone explain when to go for BPM and when to go for normal scenario(enhanced Receiver determination) in case there are multiple receivers?Please give some detailed description as I am pretty confused with this topic.

2.Also explain me the steps to configure a scenario with file as sender and 2 Idoc's at receiver end with and without condition.

Thanks in advance,

Harish.
