About Effectivity
Objects that are effectivity-managed include parts, documents, and the following manufacturing process objects: process plans (manufacturing process plans, sequences, and operations) and manufacturing resources (plants, resource groups, skills, process materials, tooling, and work center).
Effectivity is the planned date, lot, or serial number at which old versions of the object are replaced with new versions in production. You can make changes to planned effectivity settings from a change notice or a change task. When the change notice has been approved, the planned effectivities get copied over as actual effectivities on the given object.
Effectivity set on a variance is descriptive information only. No system processing occurs if you set effectivity on a variance.
When adding an effectivity value, you can specify multiple values and split ranges. For example, you could set Part 123, version B to be effective on Product ABC, serial numbers 1 through 5, and 9 through 11. For further information on the syntax of setting multiple effectivity values, see the section on syntax.
Effectivity Terminology
Effectivity Level
The product structure element that provides the context for setting serial number effectivity.
Effectivity Structure Propagation
The system action where an effectivity statement is written on child versions in a product structure to a defined configuration specification.
Effectivity Qualifier
Additional information that further defines the meaning of an effectivity statement. For example, Exact or No later than.
Effectivity Type
The kinds of effectivity that can be set on an object version. The choices include serial number, manufacturing sequence number (MSN), lot number, block number, and date. The allowable types are determined by the default trace code recorded on a traceable part.
End Item
The top part in a product structure that represents what is delivered to a customer in fulfillment of a contract.
End Item Effectivity
An effectivity statement written on a part version with the context of an end item.
Sibling Propagation
The system action where the effectivity ranges of previous object versions are modified to reflect the effectivity of a new object version.
Traceable Part
A component or assembly part that has been designated as traced by serial or lot number. You indicate a part is traceable when you create it.
