How do I configure an issue to only transfer from backlog to kanban board only with complete fields

[Aryeh Schwob]

I would like to make certain fields mandatory. When the issue is created we may not know the assignee priority etc. I want those fields to be mandatory when transferring from the backlog to the Kanban board and to not allow the transfer to be done until the required fields are filled in. Is there a way to configure that?

You can achieve this with workflow validator.  First restrict the transition from the backlog to the kanban. Then click on

Transition -> Validator-> Add Validator -> Field Required Validator->Add->Select the field required for transition-> Add error message ->Add

Thank you @Kwame Afreh for answering it so clearly!

Hi @Aryeh Schwob ,

Yes, you can have mandatory fields, here's how to set things up.

In my view, the best way to achieve mandatory fields is to create a Validator on those workflow transition that go from the backlog to anywhere on the board. 

Pair this Validator with a transition screen that allows user to enter the required fields for the best user experience.

Jira Cloud comes with a "Field Required Validator", so you should be able to get going without any apps.

Should you ever find yourself wanting to build more complex validators, there are a few apps on the marketplace that allow you to use a custom language called Jira Expressions to build almost any kind of validator. 

Anyway, hope that helps,
