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 value of the Supersede Rule option will control the serials
that have already complied with the superseded (replaced) modification. If this
option is enabled, the serials that have complied with the superseded modification
and the serials that have the value To Be Performed on its superseded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 option is disabled, 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 option is enabled 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 option cannot be enabled
together with the Supersede Rule option.
When activating a modification, the Other preliminary revisions exist
option, in the Activate Modification dialog,
is enabled if there are several revisions of the same modification in the
Preliminary status. Enable the Set other preliminary revisions to
obsolete option to set all other preliminary modifications to obsolete.
Note that modification revisions superseded by the selected modification will
automatically be set to the Obsolete status.
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.
- The serials with part numbers listed in the Assign Parts
tab will be assigned to the modification.
- If the assignment type of the modification is By Revision All
Serials, only serials with the parts revisions listed in the
Assign Part Revisions tab will be assigned.
- If the assignment type of the modification is By Serial Range,
the serial numbers defined in the Serial
Range tab will be assigned.
- If a serial is locked, it will not be assigned to the modification.
- A due calculation is performed.
- 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.
- If the Keep Perform Modification Definitions option is enabled,
serial assignment will be copied to the new revision.
- 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
Modification Details/Assign Repair
Codes tab. Instead repair codes must be added or changed on the corresponding
MRO part modification record.
