Date Effectivity
A form of effectivity where a part or configuration is defined as valid from a specific calendar date, used when changes align with time-based events such as regulatory compliance dates, model year transitions, or supplier qualification dates.
Why it matters
Date effectivity is the simplest form and is appropriate for changes driven by external calendar constraints. It works well when production schedules are predictable and the change can be cleanly aligned with a production cutover date.
