Multimapping in PI 7.31 JAVA stack

Hi All,

I am working on File to File and IDoc scenario in PI7.3.1. My requirement is that XI needs to pick the file using File adapter and based on some condition in mapping File and IDoc should be generated at target side.

Can i achieve this by using multimapping like in mapping source as File structure and Target as File and IDoc structures?

I have gone through the below link to achieve this, but could not find the extended receiver determination in the PI7.31 JAVA.

Please suggest me the best approach to achieve this.

Thanks
