Perform Due Calculation for Modification Events
Explanation
This activity is used to calculate the due date of the modification or inspection
that is to be performed on an assigned serial. The due calculation is performed
for each serial based on the average operational value per month, the effective
date and the execution intervals (i.e., Initial Inspections, Continued Inspections
and Terminating Action) which are defined on the modification.
To perform this activity select the Calculate Modification option
from the
Modification Details page or the
Define Modification
page. The calculated due dates can be viewed in the
Assign Serials tab of the
Modification
Details page. If IFS/Complex MRO is used, select the Perform Due
Calculation option from the Manage Work Scope Events
page to calculate due dates for all the events which are to be performed
during a shop visit.
Prerequisites
- A modification must have been defined. This modification must be in
the Active status.
- The serials on which the due calculation is to be performed must have
been assigned to the active modification revision.
- The active modification must have been defined as To Be Performed
on the assigned serial you want included in the due calculation. For more
information, refer to the activity
Decide if the Modification should be performed for the Serial.
- Execution plans must have been defined on the modification or inspection.
For more information, refer to the activities
Define
Inspections on Modification and
Define Terminating Action on Modification.
- An average operational value per month must have been registered for
the assigned serial. For more information, refer to the activity
Supply Operational Parameter Information.
- The date on which the due calculation is to be performed on the assigned
serial must have been defined in the Effective Date field.
- Modification 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
- Due dates are calculated for the modification or inspection which is
to be performed on the assigned serials.
- If the calculated due date is within the given number of Days
Forewarning, a pending event is created.
- If the Rescission Date of the modification or inspection is within
the given number of Days Forewarning, a pending event is created.
- The due calculation for modification events will handle events that
are included on maintenance orders not yet released.
