Define a Modification Revision
Explanation
This activity is used to define 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 event that will be executed within a
certain time limit on the given serial(s). You can also use a modification to
control one-time event 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.
Modifications can be defined in the Define Modification
page or the Modifications page. Subsequent revisions
must be created by using the New Modification Revision
assistant.
Following is a description of some of the information that can be entered
when defining a modification:
- The modification category, i.e., whether it is optional, recommended
or mandatory to perform the modification.
- The assignment type of the modification, i.e., whether the modification
is applicable for all serials of the assigned part revisions, serials for
a given serial range, or whether the modification is for documentation purposes
(e.g., user manuals for serial parts). For documentation type modifications,
only the modification definition and structure impacts will be applicable.
- Days forewarning, i.e., the number of days before the calculated due
date that the maintenance event for the modification should be created.
- The rescission date, i.e., the latest date for execution of the modification
on all assigned serials.
- The effective date, i.e., the date the modification becomes effective.
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.
- Additional information on the modification. When a maintenance event
is generated for the modification, this information will be transferred
to the Mx Event Remark field of the event.
- Enable or disable the Supersede Rule option. 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:
- If the option is enabled, you must comply with the new modification
revision regardless of whether you have complied with the previous modification
revision or not. 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.
- If the option is disabled, you do not have to comply with the new
revision if you have already complied with the previous revision of
the modification. 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. Note: The
same will apply if supersedence is defined between modifications with
different modification codes, not only revisions of the same modification.
- Enable or disable the Keep Perform Modification Definitions
option. 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. To do this, this option must be enabled. When
the new revision is activated the assigned serials will be updated with
the relevant changes. Note: The Keep Perform Modification Definitions
option cannot be enabled if the Supersede Rule option is enabled
and vice versa.
- Enable or disable the Allow Quick Reporting option.
If a modification compliance is to be done without performing a full scale
event or work order, this option can be enabled. This will enable you to
sign off the modification without performing a full order flow. If the modification
originates from an internal change request or change order, you can make
reference to the change order.
Documents can be connected to a modification by using the functionality in
Attachments. When a modification is deleted, the connection
to the document will be removed. If there is a need to delete the document itself,
this must be done manually using IFS/Document Management.
New Modification Revision
The New Modification Revision assistant can be
used to create a new revision of a modification and copy certain information
to it.
The additional information entered in the assistant, will be transferred
to the Mx Event Remark field of the corresponding maintenance
events. The Keep Perform Mod Definitions option should be enabled
if the serial assignment (Perform Modification field settings
for the modification assigned serials) should be copied to the new revision,
provided the modification category is the same for the old and new revision.
Only one revision of a modification can be active at any given point in time.
When the new modification revision is set to the Active status the currently
active modification revision will be set obsolete. A warning message will appear
when the new modification revision is to be set active and you have the option
of canceling the operation.
Prerequisites
- Modification types must have been defined.
- Modification execution level codes must have been defined.
- Maintenance time units must have been defined.
System Effects
- A new revision of the modification will be created.
- If selected, repair codes assigned to affected parts at user-allowed
sites (i.e., for the logged-in user) will be copied to the new modification
revision.
