Is the 'assignee' of a subtask by default the reporter of the 'story'?

is the 'assignee' of a subtask by default the reporter of the 'story'? is there a way this can be changed?

[Kian Stack Mumo Systems]

@Javeria Mateen, by default the assignee will be unassigned unless you have set up a workflow post function or an automation rule to set the default.

The reporter may be the one responsible for completing the subtasks, but there could be others that need to contribute as well.

Thanks,

Kian

@Kian Stack Mumo Systems No Automation rules are set, but what is a workflow post function?

[Kian Stack Mumo Systems]

Post functions are actions which execute on an issue after a transition has been executed. There are several built in post functions automatically applied to each transition, but your administrators can set their own custom post functions.

A post-function is a chunk of code that is run once a transition has been validated and confirmed (a transition is a change of status).

They are implemented in workflows in the project.  You can find these in the project settings (For company-managed, in the workflow scheme, for team-managed, they're under each issue type)

The subtask may also be getting set based on a Component being assigned to it (if these are issues in a Company Managed project).

Components can be used to set a default assignee for an issue when the Component is added to the new issue during creation.
