This forum is to discuss different features/issues of Oracle Financials modules ( GL - General Ledger, AP - Accounts Payable, AR - Accounts Receivable, FA - Fixed Assets & CM - Cash Management ).
In Order Management after you book the order, perform pick release and ship confirm by which the order lines would get populated in the Interface table.
From AR module when you run 'Auto Invoice' these lines would be imported as Invoices .
