Perform Due Calculation for Interval Maintenance Events
Explanation
This activity is used to perform the due calculation for the interval maintenance of a given serial. The
calculation will be done for the serial, based on the registered average operational value per month and the
defined maintenance plan. In addition, the due calculation will create a maintenance event when it has reached
the days of the forewarning period. The due calculation for a serial will only be done for a maintenance plan
connected to an active maintenance program. Therefore, a maintenance program that has an Active status must be
connected to the serial before the due calculation can take place. For a calendar based maintenance plan, where no
average operational values exist for the primary operational based parameter, there will under certain
circumstances only be calculated one record for recurring items.
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 interval based maintenance. The Parallel Due Calculation for
Interval Maintenance scheduled task will be used to calculate the due date for maintenance events. For more
information on the scheduled tasks, refer the online help file Adjust and Verify Background Job for Due Calculations
for Interval Based Maintenance.
To run the due calculation for the interval maintenance of a serial:
- Search for the serial for which you will run the due calculation from the Serial Maintenance page and
then click Perform Due Calculation to open the Perform Due Calculation dialog.
- Enable the Interval Maintenance option to calculate interval maintenance events. If you want to
perform due calculation for all serials in the serial structure, enable the Calculate Entire Structure
option and to perform the due calculation as a background job, enable the Run in Background option.
- When the due calculation is finished, you can view the calculated interval maintenance due dates in the
Interval Maintenance tab and view the information on the maintenance program for the calculated interval
maintenance in the Next Interval Maintenance in Structure tab in the Serial Maintenance page.
Note: Perform Due Calculation option can be selected from the Serial
Initializaion page also.
Prerequisites
- An active maintenance program with a defined maintenance plan must exist.
- An average operational value (per month) for the serial must exist.
- The serial available for due calculation, cannot have an operational status of Planned for Operation
and cannot be a locked serial.
- The interval maintenance 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
- Interval maintenance due dates are calculated for the serial.
- If the calculated due date is within the defined number of days forewarning in the maintenance plan, a
pending event is created.
- The due calculation for interval maintenance events will handle events that are included on maintenance
orders not yet released.
