change rule

Definition

Key that specifies which change procedure must be used for recipe or inspection plan maintenance.

Use

Using the change rule, you can define the following restrictions for maintenance:

Unlike unrestricted maintenance, you create a new change status on the valid-from date of the change master record. The changes are logged and can be documented in the change master record.
If you choose this option, you specify that all changes must follow a detailed approval procedure. The functionality of the change master record also applies to the engineering change order.
By defining a change type, you specify a user-defined approval procedure in the engineering change order as well as a specfic workflow.

By entering a change rule, you lock the recipe or inspection plan for all less restrictive change procedures. To revoke the change rule, you must follow the change procedure defined by it.
