 Engineering Change Management in the Classification System

Use

There are two types of engineering change management:

  • Engineering change management by Valid-from date

In the change master record for a change number, you enter a valid-from date on which changes made with the change number become effective.

Example Example

You create a change number that has January 1, 2002 as the valid-from date. All changes made with the change number become effective on this date.

End of the example.

  • Engineering change management with effectivity

In the change master record for a change number, you enter an effectivity type and the effectivity parameters.

Example Example

You define effectivity type CUSTOMER for a change number, and enter the customers for which the changes apply as parameters.

End of the example.

Prerequisites

You have created a change master record in the engineering change management menu.

  • If you want to work with validity periods, the change master record must have a valid-from date.

  • If you want to work with effectivity, the change master record must have the effectivity type, effectivity parameters, and parameter values (for example, parameter CUSTOMER with value CUSTOMER = ‘Smith’).

For each change master record, you must specify the object types that can be processed using this change number. For the classification system, object types Characteristic, Characteristics of class, and Classification are supported.

The change master record is identified by a unique change number.

Features

You can process the following classification system objects with engineering change management:

Objects

Activity

Characteristics

Create, change, delete

Characteristics of class

Assign,

delete from class, overwrite for class

Classification

Create, change, delete classification

The following restrictions apply:

  • Once you have used engineering change management to process characteristics, characteristics of a class, or classifications, you must use engineering change management for all further changes.

  • Documentation for characteristics and characteristic values is not subject to engineering change management.
