Definition
Use
You can choose one of the following options in the data model:
- Key Cannot Be Changed; No Internal Key Assignment
You need to enter the complete key when creating an entity. It cannot be changed at a later date.
- Internal Key Assignment Only
When you activate the change request (that is being used to create the entity), the system automatically assigns the key for the entity. Prior to the activation of the change request, the system creates a temporary key you can use to reference this entity within the change request. You cannot change the key.
- Key Can Be Changed; No Internal Key Assignment
You need to explicitly define the key of an entity you are creating. However, you can change it as long as the change request (in which the entity is being created) has not been activated. Once the change request is activated, you can no longer change the key.
- Key Can Be Changed; Internal Key Assignment Possible
This option is a combination of the two preceding options. Either the system can automatically assign the key of a new entity or a processor of the change request (in which the entity is being created) can create or delete the key.
- If a processor defines or changes the key, the system does not automatically derive the key when the change request is activated.
- If no processor explicitly defines or changes the key, the system automatically derives the key when the change request is activated. In this case, the automatically derived temporary key is used as the ID of the entity until the change request is activated.
Dependencies
- Internal Key Assignment Only
When this option is selected, you can optionally perform the Customizing activity Define Prefixes for Internal Key Assignment. If you do not define any prefixes, the system uses the default prefix $.
- Key Can Be Changed; Internal Key Assignment Possible
When this option is selected, you must perform the Customizing activity Define Prefixes for Internal Key Assignment.
