Have a field for multiple tasks in one epic roll up to a field in an epic

[Mona Aghamirsalim]

Imagine each Epic and Task (that is a child of the Epic) have a field called JWM Story Points. How can I have the JWM Story Points field of the epic, show the sum of  the JWM Story Points of all its children. {{issue.children.JWM Story Points.sum}}, {{issue.child.JWM Story Points.sum}} and {{issue.tasks.JWM Story Points.sum}} and {{issue.task.JWM Story Points.sum}} have not worked so far. I do know that this idea will work for subtasks -{{issue.subtasks.JWM Story Points.sum}}- for a friend of mine but I have tasks that roll up to an epic not subtasks rolling up to a task.

Sushma,

This is a little bit more complex than it looks to be

For completed (Finished) SLA Metrics you can read data directly from database, but for Active and Paused metrics SLA Metric Searcher uses some logic. To determine if an Active SLA Metric is breached you need to determine: SLA Calendar, Consumed time, SLA Goal Value and current time.

It can't be read directly from database but you may write some code to map entire logic and get actual SLA Metric values. We did it some time ago for VertygoSLA (it took a lot of time but it's feasible).

If the reporting is essential to your company, you can use SLA PowerBox add-on which provides SLA Date custom field type and let you get data directly from database (but it's paid add-on and replaces SLA functionality in JSD).
