### Perform As User

Perform As User is a configuration option in JSU post functions. It lets you choose the user who acts on the post function when it runs. When choosing a user account to run a post function, the specified user account must have the appropriate permissions to perform the actions, such as creating an issue or adding a comment.

## Example

A workflow rule is configured so the Resolve transition uses the Copy Value From Other Field post function. The value of the *Assignee* field is copied from the origin issue to the ‘TextField' field in all the issue’s subtasks. If a user resolves an issue on this workflow, the value of the *Assignee* field will be copied to the 'TextField' field after the issue is resolved.
