Variances are allowed within certain tolerance limits. These are set by your system administrator. Each time a variance occurs, the system checks whether it is within the defined tolerance limit.

If the variance is outside the tolerance limit, the system displays this in a warning message. If you do not adjust your entries, you can still post the invoice. If, however, the upper tolerance limit is exceeded, the system automatically blocks the invoice for payment. The invoice can then only be paid by Financial Accounting after the invoice has been released in a separate step.

If the variance is within the tolerance limit, the system accepts the entry. In this case, there is no need for a warning message or a payment block.
