Is it possible to set up 2 position heirarchies using Approval Management Engine ?

Hello,

We are on R12.1.3

We have a requirement where in we need to set up 2 position hierarchies for requisitions.

Is it possible ?

Say if a requisition has supplier and supplier site populated it will follow the position heirarchy A

If not it will follow position Heirarchy B

Is this possible using Approval Management Engine ?

If yes how.

Thanks in advance,

Natalie
