How to add days to the parent's due date?

[Roger Alexis Mosquera Montaño]

Hi

When the due date of a subtask is modified, I need to identify the number of days of difference between the original due date and the final due date, and then add that number of days to the due date of the parent.

How can I get it through automation?

Could you give me an example?

Thank you.

Hello @Roger Alexis Mosquera Montaño 

Welcome to the Atlassian community.

Are you working with Jira Cloud or Jira Server/Data Center?

If the URL is similar to https://something.atlassian.net then you are probably working with Jira Cloud. Alternately you can check the bottom of a Dashboard screen to see if there is Jira application version information displayed. If there is, then you are working with Jira Server or Data Center, and we need to know which version you are using.

Hello @Roger Alexis Mosquera Montaño 

To find the difference between two dates use the diff function:

https://support.atlassian.com/cloud-automation/docs/jira-smart-values-date-and-time/#Date-difference---

To add a value to an existing date field, use the plus function:

https://support.atlassian.com/cloud-automation/docs/jira-smart-values-date-and-time/#Date-plus-unit---

I haven't worked out all the details but the basic structure of the rule would be:

Trigger: Field Value Change
  Field: Due date

Condition: Issue Field Condition
  Field: Issue Type
  condition: equals
  Value: <pick the value for subtask>
Condition: Issue Field Condition
  Field: Due date
  condition: is not empty
Condition: Smart Values Condition
  First Value: {{fieldChange.fromString.IsNotEmpty()}}
  condition: equals
  Second value: true

Action: Create Variable
  <step to calculate the difference between the original and new Due date>

Branch: For Related Issue: Parent
  Condition: Issue Field Condition
    Field: Due date
    condition: is not empty
  Action: Edit issue
    Field to edit: Due Date
    Value: {{issue.duedate.plusBusinessDays(<variable name from Create Variable step>)}}
