Jira Automation to update Due Date field based on Story Points Estimate field and Start Date field.

[Vineet.Kotian]

I want to update the Due Date field of a subtask based on the Story Points Estimate field and Start Date field by calculating Start Date + Story Points Estimate and assigning the date to Due Date field.

For eg
Feb 09, 24 (Start Date) + 4 (Story Point Estimate) = Feb 14, 24 (Due Date)

My Rule:
1. Issue Trigger:
     - Issue Transitioned - To Do - In Progress
2. Conditions
     - Issue Type = Subtask
     - Due Date is empty

3. Edit Issue fields
  - Using Smart Value for Due Date field {{issue.fields.Start Date.startDate | plus: (issue.fields.Story Points * 1) | date_add_days: (issue.fields.Story Points * 1)}}

I tried this rule but it didnt give the desired result. Any help with modifying my rule will be be greatly appreciated.

Hi @Vineet.Kotian , so you are equating story points to time, 1 SP = 1 day? That is unusual. Story points generally convey a level of size/complexity. If you want time based estimates why not use Original estimate?

with that said let's try to get your rule working. Ike unsure how SP will be translate TBH.

you mentioned you did not get the desired result. What is the result? Does the rule fail or does the duedate give the wrong date? 

just off the top of my head without checking syntax or testing I offer the following.

{{issue.Due date.plusBusinessDays(issue.story points)}}

It may be the 1 SP ends up translating to 1 second. if that is the case and you want one story points equal one day you would have to multiply story point by 86,400.

Hi @Jack Brickey 

First, I agree with your ideas about story points usage.  And...

@Vineet.Kotian asked about setting the Due Date from the Start Date.  Your example seems to show the opposite: adding to the Due Date.

Kind regards,
Bill

[Jack Brickey]

Yes indeed! Thanks for keeping things accurate @Bill Sheboy . So I guess it would be...

Due date equals 

{{issue.Start date.plusBusinessDays(issue.story points)}}
