Accrual Write-Off

Hi,

Can some one from Procurement help me with the below:

1. We have a PO with 6 Lines. For Line 2 Quantity Received and Qunatity Billed dont tie. (vendor has not sent us the Invoice yet)

2. After few months we decide to Write-off the amount and use Accrual Write-Off form to write off the balance

3. Since the Line is written off we decide to FINAL Close the Line.

4. Now after some time, the vendor sends us a Invoice (for which we have actually written off)

5. We Reverse the Accrual we did in Step 2.

6. However the PO Line 2 is still in Final Close status. How do we Open this and match it to Invoice ?
