Item Relationships
You can add and view relationships between any two items using the Relationships tab. Related items can be in the same or different workspaces.
Item relationships are similar to linked items. The difference is that item relationships can be bi-directional as well as uni-directional. You typically use item relationships to cross-reference sibling items. For example, you can add an item relationship to cross-reference two different but related customers in a Customers workspace. For access from one related item to another, items are added to the Relationships tab as links.
Note: If you don't see a Relationships tab, it could be your administrator didn't enable the tab for that workspace, renamed the tab, or you do not have the required permissions. If you're not sure and need help, contact your site administrator.
