# Change Management

## Configure Effectivity

| Administrator privileges are required to configure the effectivity of objects or relations!
| The Change Management needs several configuration settings which are specific for the objects or relations that are controlled. In order to provide a flexible configuration of the change management, every individual object owns its change management level. The following levels are available: Level 0 = Change Management is deactivated Level 1 = Objects can be assigned manually to the change management Level 2 = Change management is required, when objects are released Level 3 = Change management is required, when objects are created
| When choosing level 1, the effectivity for each object or relation is defined individually. When choosing level 2 or 3, the effectivity of an object or relation is controlled by the corresponding Work Order/Work Set.
| The configuration of effectivity is to be executed on the Change Management Configuration mask (System > Change Management > Configuration.)
| The graphic above depicts the effectivity configuration for a BOM with the following settings:
Field | Description
Entity 1/Entity 2 | Indicate the objects that form a relation
View | Indicates the kind of relation between objects
Title | Indicates the name of the object or the relation
Status control | Indicates the change management level
Parallel Versioning | Allows to create parallel versions of an object version
Parallel Effectivity | The effectivity of objects overlap.
| The change management level 3 indicates that a BOM is subject to the change management when being created. This implies that the effectivity is controlled by a corresponding Work Oder/Work Set.
| If a BOM is configured to be subject to the change management, a single article must also be configured to be under the control of the change management. Otherwise the system will output an error message.
| An overview of the objects/relations that are subject to the Change Management in the standard configuration is available when displaying the Change Management Configuration mask in the list view.
| #### Integrate Customized Entities
| If the change management level (control level) of a structure is "1" and the "Allow duplicates" tickbox is activated, then it is possible to manually create objects with an identical position number.
