Manually Accepting Total-Based Differences 
Use
If an invoice contains a difference which cannot be reduced or accepted as a whole, you have to change individual items in the invoice. It can often be very time-consuming and expensive to find out exactly which item needs to be changed by which amount. To save costs and avoid loosing potential cash discount savings, you can manually accept a total-based difference to post an invoice without making any changes.
Prerequisites
Special authorization is required for manual acceptance of total-based differences. You maintain this authorization in Customizing for Invoice Verification: Invoice Verification ® Authorization Management ® Maintain Authorizations ® Post Invoices with Differences.
Procedure
When a difference cannot be posted automatically, it appears in the Invoice overview as incorrect. To manually accept the difference, proceed as follows:
1. From the Logistics Invoice Verification screen, choose Invoice overview.
2. Enter the required data.
The Invoice overview screen appears.
3. Choose Goto
® Doc. header.The document header screen appears. Here you can see the amount of the difference and how it was calculated.
4. Choose Accept differences (accept differences manually). This function is only active if you have the necessary authorization.
The system refreshes the display: The difference amount is displayed in the ManAccpdNetAmnt (manually accepted net amount) line; the Invoice Verification difference line is set to zero. The changes are not saved until you save on the Invoice overview screen.
5. Choose Copy.
The Invoice overview screen reappears. Change the Invoice Verification type to 1 or 2.
6. Save the changes by choosing Save.
When the program for the Invoice Verification type you entered is next run, the system verifies the invoice in the background.
