Terms for installment payment are used as an entry tool when entering documents in Financial Accounting. Instead of entering several line items, you only enter the data for one item. The breakdown is carried out by the system automatically by means of the payment terms.
For all payment terms that stand for an installment payment, the percentage specifications must be defined for the breakdown of the total amount. In addition, you must specify which payment terms are to be valid for the resulting partial amount for each percentage rate.
