Change Master Record 

Definition

The change master record is a master record that contains information necessary for the management and control of changes.

The change master record contains data of a descriptive character (such as the reason for the change) and control data (such as effectivity data, object type indicators). Besides this data that the user maintains, there is also data that is automatically updated by the system (management data).

Structure

The most important change master record data is grouped as follows:

·        Change header (description, effectivity data, status information)

·        Object type indicators (for example, BOMs, task lists, documents)

·        Object overviews for the different object types

·        Detail screens for the different objects (object management records)

Exactly which data is maintained depends on the function that the change master record adopts in the change process. For example, you do not need to maintain object type indicators for a change master record that has been created with the Leading change master record function.

Integration

In the SAP system, change master records are identified by a change number. Number Assignment is made according to defined criteria.

In the change process, a change number can identify change master records with the following tasks:

·        Simple change master record (with or without release procedure)

·        ECR / ECO

·        Change master record of an engineering change hierarchy

-         Change leader (Leading change master record)

-         Change package
