We can simulate payment history for a customer by assuming that that customer will pay all items due on the current day (or any day in the future). You can use the due date for net payment or the date up to which your customer could receive a cash discount. You can switch between the two types of display in the same manner as in open item display. To simulate the payment history, proceed as follows from the Customer payment history screen: 1. Choose Edit Simulation. A dialog box appears in which you can enter specifications for the simulation. 2. Enter the assumed payment date. The system proposes the current date as a default value. 3. Select either items which are due net by this date or items which are due according to cash discount terms 1. The system then selects only those items due by the specified date and according to the criteria.
