Is it possible to create sub-tasks based on labels?

Question

Hi together,

I need a logic that creates subtasks based on label entries!

Create-/Edit View Screen:
{Custom field} = [Label field]

When I update the {Custom field} with 3 label entries it should create automatically 3 sub-tasks.

For example: Labels (DEV - TEST - PROD)

Sub-task1: Summary (DEV - Sub-task)
Sub-task2: Summary (TEST - Sub-task)
Sub-task3: Summary (PROD - Sub-task)

I have absolutely no idea how I could realize this with Jira Automation. Any little help is welcome.

Thank you in advance …

Hello @Markus Zimmermann

Unfortunately the functionality you need is not yet available in Jira Data Center:

https://jira.atlassian.com/browse/JIRAAUTOSERVER-749

Advanced Branching to iterate over a list of values in a field is not available.

Do you expect the values to be in a known set of values? If so then you could set up rules to check if your custom field contains value X and create a subtask if it does. You would need to set up a rule for each possible value in the field.

Hi,

first at all it‘s Jira Datacenter!

Only if I create new Issues then I need a automated rule which creates automatically new sub-tasks.

For example, if I add a label with the value [INTERFACE] or [PANIC] or both in this specific {Custom field} and select create only in this case I want 2 new sub-tasks. And it would be great if I could add the label value also in the summary from each sub-task.

Sub-task1:
Summary: INTERFACE - Sub-task

Sub-task2:
Summary: PANIC - Sub-task

To answer your question, I have no experience with Automation.

Any little support is welcome!

Hello @Markus Zimmermann

Welcome to the Atlassian community.

Are you working with self-hosted Jira (Jira Data center) or SaaS Jira (Jira Cloud)?

Have you reviewed the Automation Rules documentation?

Have you worked with Automation Rules at all?

Do I correctly understand that DEV is on value, TEST is another separate value, and PROD is a third separate value?

When are the labels being added? Is that done only when the issue is created, or at a later date?

Is it possible that one label will be added, and then at a later date another label will be added, and you want subtask for each label?

Is it possible that a subtask with the matching summary might already exist? What should happen in that case?
