This is the documentation of JSU for Jira Server/Data Center. If you are using JSU on Jira Cloud, you can find the documentation here.
The 'Fields Required' checks whether values for specified fields are set for a given transition.
You must select mandatory fields, when configuring the transition. For example:
JSU default behaviour is to apply the context settings, this means that a field that is required by this check, but having no valid context for the current issue, wont be checked. Thus you may select to ignore the context, in that case a field will be required by this check, even if its context is not configured for the current issue.
For information on how to configure a check in JIRA, see the JIRA documentation.
A workflow is configured so that the 'Resolve' transition has the 'Fields Required' check where 'Fix Version' is mandatory. If a user attempts to resolve an issue on this workflow, where the 'Fix Version' field its value not set, the check will fail and no action will be performed.
