Activate Modification Revision
Explanation
This activity is used to activate the new revision of a
modification. When all definitions for a modification have been entered the
modification can be activated. Note: Only one revision of a modification
can be active at any point of time. Therefore, the existing active
modification revision is set to the Obsolete status when a new modification
revision is activated. When this occurs, the selection of the Supersede Rule check box will control the
serials that have already complied with the superseded (replaced) modification.
If this check box is selected, the serials that have
complied with the superseded
modification and the serials that have the value To Be Performed on its
superseded modification will also get To Be Performed for the
new
modification revision. If the check box is not selected, the serial does not
have to comply with the new modification revision. If the previous
modification revision was not complied
with, then the new modification revision will be complied with.
If the Keep Perform Modification Definitions check box is selected for
the modification revision being activated, the Perform Modification changes
(i.e., serial assignment) will be copied from the old revision to the new
revision, provided that the modification category is the same for both revisions
and there are no references to a different modification. These changes can be
seeing in the Perform Modification field in the
Modification Details/Assign Serials tab. Note: This check box
cannot be selected together with the Supersede Rule check box.
When the modification is activated, serials are
assigned to the modification and a due calculation is performed. If the due
dates are within the time period specified in the Days Forewarning field,
new pending events are generated in the system.
If the modification work will result in a part identity
change on an assigned/affected serial, the serial will be renamed to include the
new part number and revision once the modification is embodied. In order to
successfully perform the rename of a serial, the new part number and revision
for the serial must have been entered on the modification (i.e., in the
Change to Part Number and Change to Part Revision fields). For more
information refer to the activities
Assign Part Revision
to Modification and
Enter Affected Parts.
When the modification is activated, the system will perform a check to validate
the following information:
- the new part number is a valid alternate of the
old part number
- the manufacturer of the old part number is valid
for the new part number (i.e., when a new manufacturer and manufacturer part
number have not been entered)
- values have been entered for the new maintenance program if a
maintenance program exists for the new part number and revision, and the
maintenance program information for the old part is not valid for the new
part
- a value has been entered for the new maintenance group if the
maintenance group information for the old part is not valid for the new part
A warning message is generated if the new part number
is not a valid alternate for the new
part number. You are recommended to read through this message before continuing
with or canceling the activity. You will not be allowed to activate the
modification if the manufacturer, maintenance program or maintenance group
information is not valid for the new part number. Note:
These validations are also performed when a new part number is entered for the
assigned/affected part.
If post maintenance check (PMC) events have been generated as a result of complying a modification
revision, these PMC events will remain on the modification when a new revision is
activated. Whether these PMC events should be executed or removed, needs to be
decided.
Prerequisites
- A modification must have been defined. This
modification must be in the Preliminary status.
- One or more parts and part revisions must have been assigned to the
modification.
- If the assignment type of the modification is By Serial Range, at least
one serial range must have been defined for each part number.
- A terminating action must have been defined for each part number or
revision assigned to the modification if either the Next Visit in Workshop
or Next Interval Maintenance has not been specified.
- If the modification leads to a part identity
change, the new part number and revision must have been entered for the
serial. These values can be entered in the
Define Modification/Assign
Part Revisions tab or the
Modification Details/Affected Parts
tab.
- If a new structure position is being introduced by the modification
(i.e., as a structure impact), this structure position must have been added
to the template structure.
System Effects
- The modification revision is set to the Active
status.
- If another revision of the modification already exists in the
Active
status, it will be set to the Obsolete status when the new modification
revision is activated.
- If the new modification revision supersedes other modifications
revisions, these modification revisions will be set to the Obsolete
status.
- Serials are assigned to the modification and a due
calculation is performed.
- If the Keep Perform Modification Definitions check box is
selected, serial assignment will be copied to the new revision.
- If a serial is locked, it will not be assigned to
the modification.
- If the modification is due within the
specified Days Forewarning, a pending maintenance event is created.
- If the modification leads to a part identity change, the new part
number, revision, manufacturer data, maintenance program and group
information will be validated when activating the modification revision.
- A warning message is generated when the new part
number is not a valid alternate.
- An error message is generated when the
manufacturer and manufacturer part number is not valid for the new part
number.
- An error message is generated when the
maintenance program for the old part number is not valid for the new part
number.
- An error message is generated when the maintenance group for the old
part number is not valid for the new part number.
- An error message is displayed if the new structure position being
introduced by the modification has not been added to the template structure
at the time of activating the modification revision.
If IFS/Complex Assembly MRO is used:
- The modification is transferred automatically to manufacturing if the
assigned part revision has already been transferred, and affected parts are
defined for the assigned part revision. The modification is transferred to
all sites to which the assigned part revision has been transferred and to
which the logged-on user is allowed.
- If repair codes have been assigned to affected parts on the
modification, these repair codes will be transferred as well.
- An MRO modification header, MRO part modification records, and MRO part
modification repair code records will be created at the valid sites.
- It will no longer be possible to update the data in the
Assign Repair Codes tab. Instead repair codes
must be added or changed on the corresponding MRO part modification record.

Procedure
- Open the
Define Modification window
and query (F3) for your modification that is in the Preliminary status.
- Right-click anywhere in the header, point to
Status and then click Set Active.
- The Activate Modification dialog box
opens.
- If there are several revisions of the same modification in the Preliminary
status, the Other preliminary revisions exist check box will
be selected. Select the Set other preliminary revisions to obsolete
check box to set all the other Preliminary revisions to the Obsolete
status. Note that modification revisions superseded by the selected
modification will automatically be set to the
Obsolete status.
- Click OK to close the dialog box and
activate the modification revision.
