The authorization concept in engineering change management is derived from the general authorization concept in R/3. The general authorization system is described in the System Administration document.

In addition to the authorization concept of the application (such as bills of material or document management), there is also an authorization concept for engineering change management.

The authorization objects for engineering change management are assigned to the Production Planning object class (transaction SU03 – Maintain Authorizations: Object Classes).
In the standard system, the following authorization objects are defined for engineering change management:

• CC Change Master – Authorization Group (C_AENR_BGR)

• CC Engineering change mgmt - revision level for materials (C_AENR_RV1)

• CC Engineering Change Mgt – revision level for documents (C_AENR_RV2)
• CC Eng. Chg. Mgmt. Enhanced Authorization Check (C_AENR_ERW)

The following tables show, for each of these authorization objects, which fields control the user authorizations for change management.

This table shows authorization object C_AENR_BGR. This object controls, for example, whether a user can create, change, or display change masters. However, there may be certain change masters that you want to make available only to particular groups of users. For this purpose, you can define authorization groups.

This table shows authorization object C_AENR_RV1. This object controls whether a user can create or change revision levels for a material.

The authorization system is described in greater detail in the System Administration document.

This table shows the authorization object C_AENR_RV2. This object controls whether a user can create or change revision levels for documents.

This table shows authorization object C_AENR_ERW. This object controls highly specific processing of the change master record.
