Question-Integration between EAM and AP?

Hi Gurus,

I need your help. Is it possible to create an integration between Oracle EAM and Payables to the point where I am in AP entering the lines of an invoice for a particular contractor and I can determine if a work order was done for this amount? Something like the hold functionality

Situation:

We have GL, AP, PO, iProc, Inv, EAM installed. Currently for contractors, the contracts are created thru PO using a specific account code. The PO and agreement is done and during the length of that contract the contractor will use stock from our inventory and he will charge us sums (resource cost) periodically, we track the resource cost and materials thru EAM via work orders. The resource cost is linked to that account in the PO.
