Incorrect Billed Amount

1. PO is matched to an Invoice.

2. At the line level, Project/Exp/Exp Org/Type information is entered.

3. Lines of the invoice are then cancelled. Invoice header Amount is updated to 0.00.

4. Invoice is then validated and cancelled.

In essence, amounts at the Invoice level are reversed.

When we query PO from Purchasing responsibility, it is showing Billed Amount. The Billed amount should be 0 but that;s not the case here.

Is there a process that needs to be run either from AP/Purchasing/Projects that updates this ?? Or is this some kind of data corruption ?

Thanks,

Siva
