Issue Link
You can define the link type to define which issues exactly will be affected by the operation.
Since JSU 2.2.0, we introduced the value ANY. The operation will be performed on any linked issues.Parent / Sub-Task
The related issue is either parent or sub-task of each other.Epic / Issue in Epic
This is only applicable if you have Jira Software installed.
The other issue is either the epic is , related by an epic link, or it is part of an epic. This is only available if you have Jira Software installed.JQL
A JQL query will be executed to find the issues, which will be affected by the post function. You can use some placeholders in the JQL query, which will be replaced with the current field values of the issue in transition.
For help with writing the JQL query see the instructions on JQL Reference. See our JQL Use Cases for some examples.
Issue in Transition
We use the term 'Issue in Transition' when we refer refers to the issue for which a workflow condition is checked, for which a workflow validator is examined, or for which a workflow post function is performed. Or in other words, It is the issue that triggered a workflow condition/validator/post function to be executed.
Source and Destination
For Some post functions, for example, the Copy Value From Other Field post function allows allow you to define the issue in transition as the source or destination of the copy operations, while you define the other end with an issue relation.
The field value will then be read from the source issue and be written to the destination issue.
Other workflow modules do not have source and destination. So ; you just define the issue relation that will apply to that workflow module.
For example, Create a Linked Issue will just create a new issue and then connect it with some Issue Relation to the issue in transition.
...
Some of these restrictions are mentioned as 'must be' within the options to configure the issue relation.
We try to perform whatever is possible. In case of problems, the workflow module will still run but a message is entered into in the log file. See Troubleshooting for how to turn on the full logging for JSU. This is recommended while you test any new workflow configuration.
