Dear all,
* We are a small operation with sometimes no critical and/or high priority tickets in a month
* In the monthly SLA attainment report generated by Jira, ticket priorities with no tickets that month get reported as 0% attained
* Attached is an example for December of last year

* Can someone please show me a way that zero tickets for a particular priority in a month is presented in Jira reporting as 100% SLA attainment ?
* We run Jira Service Management 4.20.1 data centre/server
Any help is much appreciated.
Regards,
Steve
