Define a Modification Revision
Explanation
This activity is used to create a modification revision.
A modification can arise as a result of new technology, safety demands and/or
quality demands specified by the manufacturer or due to repeated errors and
damages. A modification can lead to the generation of a maintenance task that
will be executed within a certain time limit on the given serial(s). You can
also use a modification to control one-time task types that are to be executed
on the selected serial(s).
If the modification leads to changed functionality, serials and serial
structures can have different revisions on the documentation during the period
of time the modification program is carried out. Therefore, modifications
have a close association with revision handling on parts, template structures,
serials and serials structures with related documentation.
When a modification is replaced with another the Supersede Rule will take
effect. This rule controls the behavior of serials that have been assigned
and/or already complied with. The following general rules apply:
- The Supersede Rule check box is selected - You must comply with the
new modification revision and the previous modification revision. Serials
are assigned to the new modification (the superseding modification) and the
value in the Perform Modification field found in the Modification
Details/Assign Serials tab will be set to To Be Performed. An
exception for this instance will be when the category is Optional for which
the value in the Perform Modification field will be set to Not To Be
Performed.
- The Supersede Rule check box is not selected - You must comply with
the previous modification revision. Serials are assigned to the new
modification (the superseding modification) and the value in the Perform
Modification field will be set to Not To Be Performed.
It is possible to copy Perform Modification changes (i.e., serial assignment)
from one revision of a modification to another, provided that both revisions
have the same modification category and there are no references to a different
modification. When the new revision is activated the assigned serials will be
updated with the relevant changes. Note: The Keep Perform Mod
Definitions check box cannot be selected together with the Supersede Rule
check box.
If a modification compliance is to be done without performing a full-scale
task or work order, select the Allow Quick Reporting check box. If the
modification originates from an internal change request or change order, you
need to give the reference to the change order.
Prerequisites
- Modification types must have been defined.
- Maintenance task level codes must have been defined.
- Maintenance time units must have been defined.
System Effects
A new revision of the modification will be created.
As a result of this activity, a new revision of the modification program will be created.

Procedure
Option 01:
- Open the
Define Modification window or the
Modifications window.
- Create a new record (F5).
- Enter an identification code for the modification in the Mod Code field.
- Enter a description of the modification in the Description
field, and a revision number in the Mod Rev
field.
- In the Category field, enter the category of the modification.
Valid values are: Optional, Recommended and Mandatory.
- In the Assignment Type field, enter the assignment type of the
modification. Valid values are: By Revision All Serials,
By Serial Range and Documentation.
- Enter a value in the Mod Type field by using the List of
Values.
- In the Days Forewarning field, enter the number of days before the calculated due date
that a
task should be created.
- In the Rescission Date field enter the latest date for execution of the modification on
all assigned serials.
- Optionally, you can enter the date when the modification becomes
effective in the Effective Date field. All serials assigned to the
modification will be due-calculated based on this date. If a date
is not given here, all assigned serials will be due-calculated
from the date the modification is activated.
- In the Dur. Workshop field, enter the time needed to carry out the
modification in the workshop. In the adjoining field, use the List of Values
to select a valid time unit.
- In the Information field, enter any
additional information on the modification. Entering a value in this field
is optional. When a task is created for the modification, this information
will be transferred to the Task Remark field of the corresponding
task record on the maintenance order.
- Save the record (F12).
Option 02:
- Open the
Define Modification window or the
Modifications window.
- Query (F3) for the modification for which you want to create a new
revision.
- Right-click and then click Create New Revision of Modification. The
Create New Modification Revision
assistant will open.
- Enter an identification for the new modification revision in the New
Revision field.
- In the Information field, enter any additional information on the
modification. This could be for instance the purpose for creating a new
revision of the modification. When a task is created
for the modification, this information will be transferred to the Task
Remark field of the corresponding task record on the maintenance order.
- Click Next.
- The Copy to New Modification Revision
assistant step will open.
- In this step of the assistant, you can choose the
information you want copied to the new modification revision.
- Select the Keep Perform Mod Definitions check box if Perform
Modification changes (i.e., serial assignment) should be copied to the new
revision, provided that the modification category of both the old and new
revision are the same.
- Select the
check boxes found in the Copy Options area that indicate the type of
information you want copied. The Parts and Part Revisions check
box will be selected by default.
- Click Finish.
