Several payments can be found in one set directed for processing, while not all the payments belong to a processed item. In order to safeguard strict safety measures the program runs as follows: adds the so called "sums of other invoices" within the set of document items cleared together. The sum is then deducted from the total payments sum. If the payment is now sufficient, the tax transfer-posting takes place.

Value of the "other" invoices is defined by the sum of all the credit items of vendor invoices cleared together deducted by a sum of the respective balances, or if the invoice items are not matched with residual items, the value of "other" invoices include value of VAT (value-added tax) only.
