Post function - assign to custom user field?

[Chris Dunford]

There are post functions to assign to project/component lead, current user, and reporter. Is there any way to assign to a "user picker" custom field?

JSU plugin has a post-function "Copy Value From Other Field". You just have to copy a value from your custom field into "Assignee".

For Jira Cloud, that post-function is native and does not require a plug to use.

Thanks to both, this works (I guess I was fixated on the word "assign"). As Kimberly mentions, this functionalty is native to Jira Cloud.

This JSU plugin method just saved me big time before an upgrade I'm about to perform, so thank you Mikhail!!

We were on Jira Data Center 7.4.4 and were using a plugin marked as "Not Data Center Approved" called "Issue Alternative Assignee" (https://marketplace.atlassian.com/apps/5063/issue-alternative-assignee/version-history).

Upon upgrading to 7.13.3, this plugin is marked as "Incompatible" and I disabled it.  In doing so, UAT turned up a situation where a post function failed since it was trying to call this disabled plugin.  We already had JSU installed, so I followed the recommendation here to change my post function and voila! Back in business.

Just leaving this comment in case someone else ran into this as well.  Again, thanks Mikhail for the suggestion!
