States are not auto transitioning in 3 level hierarchy.

[Jira Billing]

3-level hierarchy in Jira: Story → Task → Sub-task

Automation 1 (Working Fine)

• Trigger: When a Sub-task transitions from any state to "Unit Testing"
• Action: The parent Task transitions to "Ready for QA"
• ✅ This automation works as expected.

Automation 2 (Not Triggering)

• Trigger: When a Task transitions to "Ready for QA"
• Action: The parent Story (linked issue) should transition to "Waiting for QA"
• ❌ This automation is not triggering even though the Task transitions to "Ready for QA."

Possible Cause

The transition of the Task to "Ready for QA" is performed by Automation 1 instead of a manual action. By default, Jira Automation does not trigger another automation when an issue is updated by an automation rule.

What should be the cause and solution for this?

Hi Jira Billing,

If there are two different rules, make sure the second one has the box check on the Rule details page to all it to be triggered by another automation rule.

Hi @Jira Billing 

By default, the actions performed by one rule (e.g., transitioning an issue) do not trigger other rules.  This is to prevent errors and run-away looping.

When you intentionally want this to happen, in the "downstream rule", enable the option "Allow Rule Trigger" in the details at the top of the rule:
