Global Variables list view
A global variable is not limited to the user session. In addition, it is not subject to user access rights. Thus, it is available to all users in the tenant. By default, the Global Variable items appear in alphabetical, ascending order. The list shows 20 items at a time. When you select one or more items, the Search bar shows the Delete option (trash can icon). Use it to delete all selected items
For Global Variables, the list view shows the following properties:
| Property | Control | Description |
|---|---|---|
| Name | text | The name of the global variable |
| Description | text | The description of the global variable, if any |
| Owner | text | The display name of the user creator |
| Lineage | link | Available starting with 2023.7.0. Opens the Data Lineage Viewer that displays a diagram with the entities referenced in the variable (upstream lineage) and entities where the variable is referenced (downstream lineage). |
| Edit (pen icon) | icon link | Opens the Edit Global Variable dialog |
| Delete (trash can) | icon link | Opens the confirmation dialog for the global variable deletion |
