Not sure if i am missing something, but i can't find a way to use my custom priorities for tasks. Can i only use the built in priorities or is there somewhere else to go and change the priorities that tasks use?
Tasks don't support the uses of custom priorities. They can only be set to one of the default priorities in ServiceDesk..
Hmmm, is there any documentation on how tasks impact SLA's. If i allow the incident to close with Tasks still open how does that affect SLA's.
I don't have a details answer for you right now about SLAs specifically but when a process closes, you should definitely make sure that its tasks are all closed.
