Small Differences
An invoice can only be posted if the balance is zero. It is very time-consuming to determine the reasons and change the individual items if the balance is not zero. So if there is only a slight difference between the debit and credit amounts, you can enter a new item to clear the difference.
This can occur automatically for small differences. In the Customizing system of Invoice Verification you can maintain a tolerance limit for small differences; if the difference is within the tolerance limits, the system automatically generates a posting line that posts the difference to a non-operating expense or income account.
You order 1 kilogram of a material costing $10.87. The invoice you receive contains a typing error:
1 KG Material SE-1000 = 10.78
When entering the invoice, you enter the amount 10.78 on the vendor screen. You could change the proposed amount from 10.87 to 10.78 on the selection screen for order items (see also
The line created automatically by the system posts the difference on the expense account for small differences. The balance is therefore zero and the document can be posted.
If you select the field Calculate tax when entering the tax information, it is not possible to automatically clear small differences. When a small balance occurs, the system does not automatically create a posting line but issues an error message about the balance.
