SRM 7.0 - PO output to backend system + via idoc to external system ( supplier )

Dear experts

We are using SAP SRM ECS 7.0 , and i do have a request

At this moment all our PO's created by SRM are replicated to Backend ECC system, and are going out from our system to supplier via email as PDF file

I do have a request that for 1 supplier the PO should not go as email ( PDF FILE ) should go to their system as idoc , is this possible ? how ?

If is not possible from SRM directly is it possible that the Backend SAP R3 system after received the PO from SRM to generate an idoc and send it to out ?

Keep in mind that we need this only for 1 supplier

We also don't receive any "inbounds" from this supplier so no electronic exchange from their system back to us.

Thanks !
