System Variable 100: Payment Terms: Allow Set Payment Due Date Prior to Invoice Date

Use this System Variable to determine if users should be allowed to set a payment due date that precedes the invoice date.

WorkBook automatically calculates the due date from the invoice date and the payment terms identified on the invoice. System Variable 773 allows users to manually change the due date. You can be prevented from picking a due date in the past, but System Variable 100 can be enabled to allow this. You can also create negative payment terms that calculates backwards from the invoice date, and it is also required for this setting when approving the invoice.

System Variable 100 is disabled by default.

It may be necessary to perform a refresh when modifying System Variable values.
