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.
Description
The 'Fields Required' checks whether values for specified fields are set for a given transition.
Configuration
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.
You can define a custom error message for JSU validators to provide a clear explanation of the situation to your users.
If you leave this field empty, a default error message from Jira will be displayed on validation errors. This might be a bit too technical, making it difficult for you users to understand the cause of the error.
See Workflow Validators to learn more about where you can define custom error messages.
Example
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.
Supported Field Types
JSU supports many different field types such as system fields and custom fields. However you should be aware, that not all field types are supported, and not in all combinations. We aim to cover the most important field types and are continuously adding and improving how different field types are supported. Some custom fields of other third-party apps might never be supported.
For that reason, you should always test anything you do with the JSU app with fields. You can try it with a free 30-day evaluation license.
