We are going to integrate between few legacy systems and Oracle EBS R12 in a new project. All these legacy systems create Purchase Orders & PO receipts which need to come to Oracle on a day to day basis. Payments on the basis of invoice matching will be done through Oracle only.
Since all these legacy systems have their numbering sequence for Purchase Order and Receipts, We are thinking how to map those numbers with PO & Receipt numbers in Oracle EBS!
Specifically, when a receipt inbound file coming to Oracle EBS and it has only reference to Legacy PO, what are the best way to create the reference to already created PO in Oracle for them?
