Organizations or Individuals added to the address book can be made Inactive so they no longer show up in vintrace as a selection option.
For logins that allow access to vintrace, making their entry inactive also disables their access.
Open the Address Book, find the Organization or Individual and select that entry.
Click Inactive and Save.
Find an inactive contact
In the event that you need to see inactives or need to re-activate a contact, click Show active contacts only.
This is useful if you try to create a new entry in the Address book and an error message informs you that the name is already in use.
