Hi Community! I would also like to draw your attention to the fact that Linked Items and Linked Issues are distinct. The linked item is part of the JPD system field (formula type) and is not applicable to JSW projects.
JPD System Field Details(Linked items)
This field is specifically designed to track the number of work items associated with JPD ideas. I am attaching a screenshot for your reference from a test JPD project showing the count and description of the custom field, which results in an error on the screen for JSW projects:
Message on JSW screen when adding JPD field (Linked items)
Custom Field explaining the field type and supported Product
How it looks in JPD projects
The most common use case where a Customer wants to use this field is to see if the field is populated before allowing users to move ahead with the transition.We have an open feature request to support Linked issue(s) for the field to better support in validators/conditions, as the field does not appear in validators.
So, if you are trying to block a transition when the work item does not have linked items, and based on this assumption, I tested an option to add a restrict transition rule. This rule allows you to check if the numbers are greater than a value before allowing transition, as shown below:
The only caveat is that this workaround will remove the transition on the configured status without providing any warning to users.
As a workaround, you can use a read-only text field on the screen to give some notification.
I have attached a video snippet of the setup, where the "Todo" transition will only be available to a user if there are linked issues.
