Perform Due Calculation for LLP Events

Explanation

This activity is used to perform the due calculation for LLP events for a given serial. The calculation will be done for the serial, based on the registered average operational value per month and the life limited information defined for the serial. In addition, the due calculation will calculate the remaining life and drop-dead date and create a LLP event for the given serial, provided the serial part number is defined as a life limited part and it has reached the days of the forewarning period.


Apart from manually performing the due calculation for a serial (as described in this activity), scheduled tasks exist to automatically calculate due dates for all life limited serials. The Life Limited Part Calculation scheduled task will be used to calculate the life limit of all serials defined as life limited parts. For more information on the scheduled tasks, refer the online help file Adjust and Verify Background Job for Calculations of LLP Events.
