This is probably the most-requested notification of all: being informed about a volunteer cancelling her own assignment.
Assignments cancelled in VSys One versions prior to 2.1 don't generate the "transitions
" records needed for this event to work; the assignment must be cancelled by version 2.1 or later.
If you just make a new assignment with a status of Cancelled by volunteer, VSys won't detect that as a "Self-cancelled assignment". Why? VSys doesn't look at the current status of the assignment when it's first searching for records to use here, instead it looks for records which once had some status other Cancelled by volunteer but now have one that is Cancelled by volunteer. (That also means that an assignment whose status was changed by an older version of VSys One won't qualify here, either.)
VSys doesn't know that the volunteer herself did the cancellation, instead it detects that the assignment's status was changed to Cancelled by volunteer within the Cancelled between window.
One notification is generated for each assignment meeting your criteria here, each with the volunteer's name and information about the assignment.
