When you delete an attribute, model options determine whether or not the corresponding data items are also deleted:
| Model options selected | Result of deleting an attribute |
|---|---|
| Unique Code and Allow Reuse | Does not delete corresponding data item |
| Unique Code only | Does not delete corresponding data item |
| Allow Reuse only | Deletes corresponding data item if it is not used by another entity |
| None | Deletes corresponding data item |
