Wdesk allows you to create custom units for XBRL tagging. There may be circumstances where you may want to deprecate custom units. To deprecate a custom unit is to designate it as no longer being used.
Using XBRL Fact Properties
With XBRL turned on, click on the gray X (Fact Properties)icon in the lower right-hand corner of the main window. The XBRL Fact Properties panel opens at the bottom of the editor.
In the Unit drop-down, select the unit you wish to deprecate. In this example, store is used. Click the blue circle.
The XBRL Unit Information box will be displayed. Click the Edit button.
Editing a Unit
You can now edit the custom unit information, or deprecate a unit entirely. Click the Deprecate (i.e. - should not be used) button.
The unit is now deprecated. If you check it in the XBRL Fact Properties box, the Unit drop-down box will denote the deprecated unit with a (Dep) before the unit name.
