Removing a single item from a relationship

As needed, you can remove a related feature or table record from a related feature. This can occur when you need to change the table record or feature with which another feature is related. For instance, you may need to remove a relationship between a feature and a table record because the table record is related to a different feature. To create a relationship between a different feature and the table record, the relationship must be removed between the current feature and table record.

Steps:
  1. Start ArcMap.
  2. If necessary, load data in the map.
  3. On the main menu, click Customize > Toolbars > Production Editing.
  4. Click the Production Start Editing button Production Start Editing on the Production Editing toolbar.
    NoteNote:

    The Manage Features and Create Attributes, Update Attributes, or Metadata Attributes windows automatically appear when you start an edit session using the Production Start Editing tool.

    TipTip:

    If the Create Attributes, Update Attributes, or Metadata Attributes window does not appear when you start an edit session, click the Show/Hide Attributes button Show/Hide Attributes on the Manage Features window.

  5. Click the Update tab on the Manage Features window.
  6. Select the feature for which you want to remove a related feature or table record.
  7. Click the plus sign (+) to expand the feature node and view the relationship class.
  8. Right-click the relationship node you want to remove and click Remove From Relationship.
TipTip:

If the field being used as the foreign key cannot accept null values, the item cannot be removed from the relationship.
