Add or modify an element effectivity

You can add and modify element effectivities using date ranges or unit numbers. You can also create new shared effectivities, and understand how effectivity changes can impact the element visibility. You can create an element effectivity using a range of dates, a unit number or a range of units. You can also update an existing element effectivity.

Add an element effectivityProcedure Set an active change notice to track a Usage BOM.

Select one or more elements and click Add
