payements in procurement contracts 11.5.10.2

Hi

I need information about the following:

I need some inputs from you on following points : Integration of Procurement contracts with payables:

 

1.        How to make payment of procurement contracts to service providing supplier?

2.       I believe this can be done thru ERS – Evaluated Receipt Settlements – which is staged payments in payables – payment against completion of milestones defined in contracts, But how this is achieved in oracle apps?

3.       Concurrent request to transfer procurement contract date to payables? Like in purchasing we have concurrent request – pay on receipt auto invoice ….which request pushes procurement data into payables?

 

I would appreciate if you can share your knowledge on these points.
