How to change issue assignee to a value from a custom field in JIRA

[ianvanzyl]

I have created a custom field "Reviewer" and made it a single-user-picker and configured to filter on a specific group. This field is assigned during a post function whilst transitioning to the next stage.

I require that "Assignee" field be changed to the selected "Reviewer".

I have read the info from https://confluence.atlassian.com/jirakb/how-to-change-issue-assignee-to-a-value-from-a-custom-field-in-jira-855542108.html BUT it does not explain how this can be implemented.

Please advise how this can be implemented as part of a post function on a workflow transition.

Hello Ian,

As far as I understand, you need Assign issue to the user in custom field post function in Enhancer Plugin.

If you want to change an assignee by using this KB, then you have to connect to the Jira database and make changes by executing SQL queries in the KB. 

If you want to automate the process (it is not only once done job), I would not advise you to use the KB. Better develop a plugin or use available plugins to accomplish this tasks.
