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this occurs, the selection of the Supersede Rule check box will control the serials that have already complied with the superseded (replaced) modification. If this check box is selected, the serials that have complied with the superseded modification and the serials that have the value To Be Performed on its superseded modification will also get To Be Performed for the new modification revision.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:

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.
