Deleting Displays or Referenced Objects

How to delete Displays or Other Objects

1. Navigate: Go to Displays / List.
2. Select and Delete: Choose the Display to delete and click the Delete button (X) on the DataGrid toolbar.

 For other objects, follow a similar procedure in their respective configuration tables.

2. Type and Find: Enter the object name to search for its references. Example: Searching for Display.Logon shows all locations where Logon is used.
