To Edit a Join

After you create a join, you can change the settings you specified when you created it. You can remove one (of multiple) joins from a feature layer, or remove all joins from the feature layer at once, restoring the properties for that layer to its native data only.

To modify a join

1. In Display Manager, right-click the feature layer with the join to modify, and select Manage Joins.
2. In the Manage Layer Data dialog box, select the join to modify, and click Edit.
3. In the Edit A Join dialog box, change any settings.

   The settings are the same ones you used when you created the join. For example, you can change this join from One-To-Many to One-To-One to get rid of extra features created by the original join.

4. To delete one (or multiple) joins for this feature layer, click the join to delete (use Ctrl or Shift to select multiple joins). Click Delete.
5. When you are finished, click OK.
