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.
