Whenever a document is restarted or sent back, the route needs to partially or completely repeat itself. The first time the document is routed. the route is considered to be in “stage 1”. Subsequent routes are called stage 2, stage 3, etc. When other changes are cleared, a checkbox at the bottom (normally disabled) lets you know you are seeing only the current or active stage and that other stages exist.
The Seq. number is now preceded by the Stage number. 2:1 = stage 2, route 1
