Block Initial transition if no subtask is created in issue

[priyanka]

Hi All,

We are trying to block Initial transition if no sub-task is added to the story: For this we want when issue moves from to do to in progress it should check if subtask is not created under story it should block the transition. We are not able to find such condition in existing jira WF conditions.

Any suggestions or guidance would be appreciated.

Hi @priyanka 

Assuming this is for a company managed project, you can do this with a custom field, automation and a workflow validator...

Custom Field

The custom field will be used as a flagging mechanism that will serve as the catalyst for the workflow validator. Don't add the field to the screen, but it needs to be part of the project's field configuration.

For illustration purposes, I'll call the field Admin.  If the field is empty, the validator won't let the transition occur.

Automation

Use automation to set the Admin field (I'm using "Passed") whenever Sub-Tasks are created so it can pass the validator logic:

• TRIGGER: Issue Created
• CONDITION: Issue Type = Sub-Task
• BRANCH: Parent 
  • ACTION: Edit Issue - Admin = Passed

Validator

On the desired transition set up your validator like this:

• Field Required Validator
  • Fields required for this transition: Admin
  • Error Message: The error message you'd like your team members to see

Thank you @Mark Segall that works well if we have to achieve this using native functionalities of jira.

But what if someone creates a subtask and deletes it before moving to in progress transition ? I think this would set the value and we can by pass the validator

Hi @priyanka - You could create a separate automation for Issue Deleted...

• TRIGGER: Issue Deleted
• CONDITION: Issue Type = Sub-Task
• BRANCH: Parent
  • CONDITION: Related Issues Sub-Tasks are not present
  • ACTION Edit Issue - Clear the field
