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with the superseded (replaced) modification.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superseded modification and the serials that have the value To Be Performed on its superseded modification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superseded by the selected modification will automatically be set to the Obsolete status.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.
