Several of JSU's workflow modules provide the option the 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.
...
- Copy Value From Other Field Post-Function there should be only 1 source issue. Otherwise it is not clear from which the value will be read. (The current implementation will just pick one of them and ignore the rest. Which one is not defined - sort of random.)
- If you use Create a Linked Issue Post-Function 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.
We try to perform whatever is possible. In case of problems, the workflow module will still run through, but write a message into the log file. See Troubleshooting how to turn on the full logging for JSU. It might be a good idea to do this while you test any new workflow configuration to make sure you're not missing any thing.
