Active
When Active, a particular format will be available for use within the system. De-activating a format that is currently associated with a Purchase Order (PO) will have no effect on that PO (that is, that format will continue to be used for that PO). De-activating a format indicates that it can no longer be associated when defining a PO.
Essentially, de-activating a format prevents it from being associated with anything that it is not already associated.
