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

Question

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 @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,
