It is possible to create an infinite number of statuses within an ExtraView installation. This can make it difficult to view and set the status change rules on a single screen, as the matrix displayed can grow very large, both horizontally and vertically. Commonly, business areas will use the AREA field as a parent in an allowed value relationship, and the STATUS field as the child in the same relationship.
The Status Change Rules screen will restrict the statuses shown to the statuses that are the children of the current business area. This makes the screen much more manageable.
At the same time, it is possible to use security permission keys in any valid combination of user roles and business areas to turn off the status.
A problem may arise, if you restrict a valid status change transition, then turn off the security permissions, or alter the allowed values for the allowed transition, in that you will no longer see the checkbox for the transition on the screen. To facilitate the management of your metadata under these conditions, the status change rule screen has three checkboxes, which will turn on hidden transitions, allowing you to check for incorrect settings.
View All – This will turn on all the checkboxes, irrespective of permissions, and allowed values
View Disallowed – This will turn on the checkboxes that were omitted due to the allowed value relationship
View Unpermitted – This will turn on the checkboxes that were omitted due to security permission settings.
