Perform Due Calculation
Explanation
This activity is used to start one or several due calculations for a specific serial. The valid options to run
are:
- Due calculation for interval maintenance events
- Due calculation for LLP (life limited part) events
- Due calculation for modifications events
- Recalculation of PMC (post maintenance check) events
- Recalculation for fault deferrals
The due calculations can be run for the entire serial structure or just for the serial itself. There is also an
option to run the calculations as a background job and this is recommended if the calculations are to be run for
the entire structure.
You can perform this activity for a selected serial by opening the Serial Maintenance page and
selecting Perform Due Calculation option.
Note: When the due calculations are finished, you can view the calculated due dates and values
for all types in the Serial Maintenance page besides for the fault deferrals. Fault deferrals can be
viewed in the General tab in Manage Fault Informtion page.
Prerequisites
- The serial to be calculated, cannot have an operational status of Planned for Operation and it cannot
be locked.
- An average operational value (per month) for the serial must exist.
- To run the due calculation for interval maintenance, an active maintenance program with a defined maintenance
plan must exist.
- For life limited parts to be calculated, life limited information must be defined for the serial.
- For the modification due calculation to be run, an active modification must have been assigned to the
serial.
- To run the calculation for PMC events, an event must exist and a post maintenance check definition must have
been set up for it. The event must have been completed and the serial must have reached the limit that triggers
the post maintenance check.
- For the fault deferral calculation to run, a fault with fault deferral information enabled must exist for the
serial. In addition, the fault deferral must have been approved.
System Effects
- Due calculations for the serial will be run to calculate due dates and values.
- Pending events will be created if the criteria for when an event is to be created is fulfilled.
