Business Events to Capture CREATION and UPDATE on Purchase Order and PO Receipt

Hi ,

We have a business requirement is to transfer the Standard Purchase Order and PO Receipt data from Oracle EBS R12.2 to another Oracle EBS R12

whenever -

a) Purchase Order is created and Approved

b) Any changes to the Purchase Order at header, Line, Shipment or Distribution level on specific fields(Price , Quantity etc)

and is approved.

c) Purchase order is Closed or cancelled at Header Level.

Can some one let me know if there are any Business events available to Capture CREATION and UPDATE of Purchase Orders.

Thanks,

Venky
