I have specific requirements to set SLA:
Time Of Resolution :
1.Resolution time is duration between creation of ticket to ‘Completed’ status
"it can be done setting SAL start on "issue created" AND stop on "Resolution:set"
2. The duration of ticket in pending status ‘Awaiting customer information’ should not be included in resolution time.
"set up Pause on "Time is not counted during when waiting for customer response"
IF a ticket is re-opened it should continue from the existing SLA calculations
"Not sure how to start SLA clock again when resolution is cleared and the time clock should start "when clock was stop"
