This is the documentation of JSU for Jira Cloud. If you are using JSU on Jira Server/Data Center, you can find the documentation here.
The 'Date Compare' precondition compares the values of two date fields on the issue. For example, one field must be greater than the other.
You must select the two date fields and the comparison function for the check, when configuring the transition. For example:
A workflow is configured so that the 'Resolve' transition has the 'Date Compare' check where 'Resolved Date' > 'Due Date'. If a user attempts to resolve an issue on this workflow where the 'Resolved Date' is after the 'Due Date', the check will succeed, and a comment will be created about the lateness of the resolution.
Supported Field Types
In its different modules (especially those for workflows), the JSU app supports many different field types. System fields, as well as custom fields.
However you should be aware, that not all field types or all combinations are supported. We think we cover the most important field types and are still continuously adding and improving which, and how different field types are supported. But the one you need might not work (yet).
We recommend that you test JSU with fields to see if it is compatible with your system. Our evaluation license gives you 30 days free trial.
