Make a custom field mandatory based on another field value on Jira Cloud

[Angela Salunga]

I want to require the custom field RCA (Root Cause Analysis), but only for Priority = Highest or High.

How do I create this in JIRA cloud?

Hi Angela - Welcome to the Atlassian Community!

The short answer is that you cannot do that very easily in Jira Cloud. 

The only option I am aware of is:

1. Create two transitions in your workflow for the point you want to make sure that RCA is populated (like the transition to Done). 

2. For one transition, place a condition where the Priority = Highest or High. 

3. For the other transition, place a condition where the Priority != Highest or High.

4. Then place a validator on the transition in Step 2 above to make the RCA field required. 

It's not pretty but it should work for you.

Hi John, thanks for the quick answer. I tried your suggestions, but it shows me 2 available transitions now - ideally only 1 transition should appear depending on Priority field value.

These are the conditions for both RCA and Non-RCA:

In the second transition (Ready for QA) change the heading from Any of the following conditions to All of the following conditions.   :-)

It works, thanks John!
