Perform Due Calculation for LLP Tasks

Explanation

This activity is used to perform the due calculation for LLP tasks 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 task 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 to the activity Adjust and Verify Background Job for Calculations of LLP Tasks.
 

Prerequisites

• An average operational value (per month) for the serial must exist.
• For life limited parts to be calculated, life limited information must be defined for the serial.
• The serial available for due calculation, cannot have an operational status of Planned for Operation and cannot be a locked serial. 
• The LLP tasks that are in a planning state (i.e., in the Planned in Scope, Incomplete or Under Preparation status) must be connected to a maintenance order that is not yet released.

System Effects

• When the serial part number is defined as a life limited part (LLP) and the due date calculated is within the defined number of days forewarning, the calculation creates a maintenance task for the serial.
• The due calculation for LLP tasks will handle tasks that are included on maintenance orders not yet released.
