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 Window' checks whether the value of one date field falls within the range/window of another date field. Note: The date checking is only one-way, i.e., it only looks forwards, not backwards.
You must select the two date fields and the window period, when configuring the transition. For example:
A workflow is configured so that the 'Close' transition has the 'Date Window' check. The 'Resolved Date' is checked using a window of 5 days with respect to the 'Created Date'. If the issue is resolved within five days of being created, a comment will be added with the text "Quick Win!".
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.
