Posting Total-Based DifferencesYou can use this process to post invoices containing variances. For example, the vendor invoices you for more than agreed in the purchase order. In Invoice Verification, the system determines a difference between the net total of the invoice items and the invoice amount less taxes and unplanned delivery costs, when the invoice is posted.
When invoices contain small differences, it can often be too time-consuming and therefore costly to find out the reason for the difference. Instead, the system can post the invoice with the difference if the difference is within pre-defined tolerance limits. This would be done for Invoice Verification where there is no item check, in the background or online.
Whether a difference is posted and how it is posted depends on how your system is configured in the Implementation Guide (IMG) for Logistics Invoice Verification:
In Customizing for Logistics Invoice Verification, you can also configure a tolerance limit for small differences. For more information, see Posting Small Differences .
The following options are available:
If the invoice does not meet the prerequisites for total-based invoice reduction or total-based acceptance, the system reacts in one of the following ways:
An error message appears if you are verifying the invoice online
The invoice status is changed to "verified as incorrect" if the invoice is being verified in the background
