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.
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 events 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 event for the serial.
- The due calculation for LLP events will handle
events that are included on maintenance orders not yet released.

When the due calculation is finished, you can view the calculated drop
dead date for the serial in the Serial Maintenance/LLPs in Structure
tab.
If IFS/Complex MRO is used, the following procedure can be used to calculate
due dates for the LLP events which are to be performed during a shop visit:
- Open the Maintenance Event Summary window or the
Reconfigure Work
Scope window and query (F3) for the overhaul object and/or the
MRO work order number you want.
- Right-click anywhere in the header, and then click Perform Due
Calculation.
- The calculated due dates can be viewed in the
LLPs tab found in the Maintenance Event Summary window and in
the Reconfigure Work Scope window.
