Hi Every one, I cannot match credit memo to standard invoice, the match button when pressed is only given option for Purchase order, their is no option To select an invoice to match to.secondly the quick match button is greyed out, pls guys i need urgent help about this.

You can match credit/debit memos to invoices in the Invoice Workbench
Quick Invoices window does not allow you to do that.

You can two options available in R12 to perform the match.

Using Quick Credit functionality:

1: Create a credit memo in the Invoice WorkBench. Enter a Negative amount.
2: Navigate to the Quick Credit checkbox. Check this box.
3: In the Next field enter the Invoice Number of the invoice you want to match this memo to.
4: Save your work. CTRL+S

Regardless of the actual amount on the credit memo, invoice lines and distributions will be created from the original invoice's lines and distributions.


Using Correction Functionality:

This is how matching was done in 11i.
In Release 12 an invoice match is considered a correction and is done using the Correction button.
Do not use the Match button. That is for performing the matching with POs.

1: Enter a Credit/Debit Memo in the Invoice Workbench. Enter a negative amount. Do not manually enter the distributions.
2: In the Match Action field scroll to Match Action field. Using drop down select Invoice.
3: Click on the Correction button.
4: Enter search criteria for the invoice, in the Find Documents for Correction window. Click on the Find button.
Payables navigates to the Invoice Corrections window.
To see more information about an invoice, you can select it and click on the Invoice Overview button.
5: Select the invoice and enter a Credit Amount.
You can do the line level matching by clicking on Select Lines button.
Select each invoice line you want to match to and enter a Credit Amount.
6: Choose the Correct button to correct the invoice.
To review the new invoice lines, choose the lines tab from the Invoices window.

Thank you very much Hassan
