Understand what effectivity is, why it matters, the common types, and how Teamcenter or AWC uses it to filter valid structure.
What is effectivity?
Effectivity defines the validity of a part, BOM line, or configuration. It answers a simple question: for which date, serial range, unit range, or variant is this valid?
Why should we use effectivity?
to control variants correctly
to avoid using the wrong part in the wrong product
to support date-based and serial-based validity
to reduce duplicate structures
How many types of effectivity?
Date effectivity — valid between dates
Serial effectivity — valid for serial ranges
Unit effectivity — valid for production unit ranges
Variant effectivity — valid for option or feature combinations
How to do it in Teamcenter or AWC
attach effectivity information to BOM lines or occurrence data
store the correct validity conditions
open the structure in a chosen context
let Teamcenter/AWC filter the visible valid configuration
Effectivity is configuration intelligence. It makes one structure behave correctly for different situations instead of forcing many duplicate structures.
