Several of JSU's workflow modules provide the option to define the scope of the module on some related issues.
For example, instead of copying a field within an issue during a post function, you might choose to copy it to a sub-task.

Types of Issue Relations

The related issue will be found by one of the following Jira concepts:

• 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.

• 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 writing the JQL query please follow 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 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, the issue that triggered a workflow condition/validator/post function to be executed.

Source and Destination

For example, the Copy Value From Other Field Post-Function allows 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.

Restrictions

• Copy Value From Other Field Post-Function: there should be only one source issue. Otherwise, it is not clear from which the value will be read. (The current implementation will just randomly pick one of them and ignore the rest.)

• If you use Create a Linked Issue to create a new sub-task, you must also configure this post function to create the new issue as an issue type of a sub-task and make sure the target project is the same as the one of 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 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.
