Below is the step for the scenario
Purchase Order created → contains multiple items.
Update Qty. to Receive → only for one item, and post Receive and Invoice. Now the PO is partially received & invoiced.
Go to Posted Purchase Invoice → create a Corrective Credit Memo (adjustment note) for the received item, reversing the amount. This cancels the financial posting for that item
when Check the original Purchase Order → see that the Qty. to Receive for that item is restored to the same amount as before. Is this the normal behavior of BC ?
