# Creating Unit Links

In Create Unit Links the user is able to link two or more units (representing distinct physical units or virtual units). Linked units appear as one unit in the ToolsNet UI. When linking two or more units, one of the units is selected as the included unit and the other as the hidden unit. The data of the included unit will be data that is displayed for the linked unit in the ToolsNet UI. Hence, no data merge of the linked units are done.

It is only possible to create links between units using the same root in the tool structure.

See the outcome of linking units in the following example:

All results connected to the linked units will appear to be connected to the included unit. Only the included unit of the linked units will appear in the tool structure. When selecting an included unit in the tool structure, the results from all linked units will be part of the search.

## Adding Unit Links

1. In the Administration drop-down list, select Manage units and then select Create unit links.

2. In the Select display unit window, select a unit to be displayed in the structure, and then select Next.

3. In the Select included unit(s) window, select the unit, or units, in the same root structure, and then select Next.

4. In the Summary window, check the displayed unit and the Included unit, and then select Finish.

## Unlinking Unit Links

1. In the Administration drop-down list, select Manage units, and then select the unit links to unlink.

2. Select the Unlink button .

The user is able to unlink already linked units. When the previously linked units have been unlinked, they appear in the ToolsNet UI exactly as before the linking took place.

## Viewing Unit Links

If Active Directory (AD) is enabled, you can see Unit Links on the Manage Units page only when a structure named Unit Links exists.

If AD is disabled, users can view Unit Links without creating this structure.
