Engineering Change Management (LO-ECH)

An object's (e.g. BOM item) processing status. The system generates a change status when you change or create an object with reference to a change master record for the first time

The validity criteria are defined in the change master record. A change status therefore has either date validity or parameter effectivity: Parametergültigkeit:

• Date Validity

A change status's validity is only dependent on the date. All change statuses follow in a chronological sequence. A change status's validity period starts on the valid-from date of the change master record, with which you generate the change status, and finishes immediately before the valid-from date of the change status following. If there is no change status following, the change status's validity is open-ended.

• Parameter Effectivity

A change status's effectivity depends on criteria, which you can define as you wish. The change statuses do not have to be in a chronological sequence. When you enter a parameter variant, the system determines whether the change status is effective.
