Automatically update original estimate of parent ticket based on sum of sub-task estimates

[Angela Salunga]

I am using Original time estimate as estimation statistic instead of story points to calculate velocity. During planning, we put time estimates in subtask level. How can the parent ticket be automatically updated with the sum of subtask estimates?

Thanks

[Alexander Pappert]

normally the parent task has all the subtasks values as a sum

subtask:

original estimate

paren task:

Σ original estimate

in JQL view, just ust the fileds with the Σ (they are also working for the subtasks)

Thanks for responding, I somehow got it figured out yesterday using the automation rules. I used a "start of sprint trigger" for this rule to be executed and original estimate to be populated based on the sub-task estimates:

Rule pasted in your previous comment, is it complete or any prefix is missing?

Because construction of rule doesn't start with condition.
