This activity is used to connect a part revision to a deferral item code. The connection defines the maximum allowed deferral period for a given part revision. Item codes can be connected to a part revision in the Deferral Definition/Revisions per Item tab and the Serial Part Revision/Deferral Definitions tab.
If the item code is also listed on the Functions per Item tab, the item code can be used only when the fault is reported with a reference to that function number.
Note: Most failures (faults) are a result of excess usage. To be able to report and trace faults connected to shop work, you should make a connection to the appropriate deferral lists for the actual serial parts.
