PeopleSoft Overdue Processing behavior

In PeopleSoft Receivables 9.1 PeopleBook, for Overdue Charging Setup 1 Page, 2 of the check boxes are described as shown below:

One Time Charge Flag

Select to indicate whether the Overdue Charges Application Engine process (AR_OVRDUE) should create an overdue charge only once or multiple times by checking for a last assessed date. If you select this check box, the process creates an overdue charge only once for an item; otherwise, the process continues to create overdue charges until the item is closed.

Assign Once Per Item

Select to have the system check to determine whether any overdue charges exist for any of the current items that qualify for overdue charging for this specific overdue charge ID. If a charge exists for one or more items, the system does not calculate a new charge; however, the system calculates this type of overdue charge for any qualified items that do not have any charges assessed against them. After these charges are assessed against these items, the system prevents them from being charged again.
