Manually Accepting Total-Based Differences 
Use
If an invoice contains a difference that 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 losing potential cash discount savings, you can manually accept a total-based difference to post an invoice without making any changes.
Prerequisites
You require special authorization to enter a total-based acceptance manually: You can maintain this in Customizing for Logistics Invoice Verification: Logistics 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:
The Invoice Overview screen appears.
The Logistics Invoice Verification screen appears. On this screen, you can see how large the difference is in the screen area Balance, for example.
The system accepts the difference and schedules the invoice for background verification. If tolerance limits are exceeded, the invoice is blocked for payment. When the program for verification in the background is next run, the system verifies the invoice in the background.
The Invoice Overview screen reappears. Save the changes by choosing
Save.
