Question:
What does the "SLA_VIOLATION" column store in the Call_Req table?
Answer:
The attribute "SLA_Violation" in the Call Request table an integer which is the count of the number of times the SLA's on the request have been violated.
For example, if "sla_violation=1", then it means for this request, the SLA was violated once.
If you have the Action Macro "Set SLA Violation = Violated" associated to the ticket through a Service Type Event, this count will increment each time the SLA is Violated.
