天数限制
Day of the month up until which the corresponding terms are valid.
Use
For terms of payment which depend on whether or not the baseline date is after or before the 15th of the month, you can define a two-part payment term under the same terms of payment key. The terms of payment key is expanded by the day limit entered here. Thus there are two entries in which different terms can be specified.
Example
The following terms of payment require you to enter a day limit:
Documents with an invoice date on or before the 15th of the month are payable on the last day of the next month
Documents with an invoice date after the 15th of the month are payable on the 15th of the month after the next month.
