PO Status not getting update to Fully Billed when PO is fully billed

Hello Gurus,

The PO status does not update to "Fully Billed" when thePO is fully billed, but the Vendor bill includes a split line to account for tax. This appears to prevent the system from recognizing the PO as fully billed.

Scenario:

PO# 1001, Status —> Approved by Supervisor/Pending Bill

Line → Quantity 1, Amount 20000

Bill # B1001, Status —> Paid

Line 1 → Qty .8, Amount # 16000

Line 2 —> Qty .2 Amount # 4000

We are expenting the status of the PO to "Fully Billed". How can I handle this scenario to add tax in the bill so that the status should show "Fully Billed".

Thanks

BN
