How to create an auto assign to previous assignee in Jira?

[Alex Savin]

I don't know how create auto assignment to previous assignee using custom field and post function when I change issue status (or dragging it to other status column on the board). Here, at this community a read other comments, but there is still no clear understanding except "create custom field" and use post function.

Can somebody explain me how to do that in detail? Like "chose that menu, click certain button, then go to some settings etc"? I can use post function to assign next assignee, but don't know how to assign previous.

Here I illustrate what I mean.

Thanks in advance for help.

Hi Alex, 

do you have the "Jira Misc Workflow Extension" or the "Suite Utilities for Jira" app? You need a post function to copy a value from a custom field to the assignee field. That is not working out of the box.

If you have one of these, I can give you a step-by-step solution. 

[Alex Savin]

No, I don't have, but I thought there is no need of third-party plug-in and it is possible to resolve this question using Jira tools.

So, I can use auto assign to next user but can't use auto assign to previous (last) without any plug-ins?:)

[Thomas Schlegel]

Not as far as I know. You have to put the actual user in a custom field, every time you make a transition in our workflow. That's ok with Jira out-of-the-box.

But for copying the user from the custom field to the assignee field, there is no function in Jira.

[Alex Savin]

Ok, I get it. Can you describe how to do that using JMWE?)

[Thomas Schlegel]

I'll do tomorrow. For today, I'm out of office.

Thank you, Thomas!

So here is what you have to do:

• open http://<your-jira-url>/secure/admin/ViewCustomFields.jspa
• Click on "Add Custom Field"
• Select Field Type "User Picker" and click "Next"
• Name your field "Last Assignee" and click "Create"
• Do not associate any screens on the following page (the field is just used internally and shouldn't be set manually)

And now to the workflow:

• Edit your workflow
• Add the following postfunction to every transition:  "Copy Value from Field to Field" - Copy the Assignee to "Last Assignee"
• In the transition where you want to assign the issue to the last assignee, just use that postfunction the other way round

But, if you have the Jira Misc Workflow Extensions, there is another postfunction that is much easier to use: "Assign to last role member" - you can assign the issue automatically to the role member, who had the issue assigned before. With that postfunction, you don't even need a custom field! I haven't tested that function up to now, but I think, this is exactly what you need.

Thank you very much, Thomas!

Yes, thank you @Thomas Schlegel, very useful!

This can also be done using Assign to last role member in script runner post function

Please do a little more than say oh yes I have an awesome idea but i will not tell you

Hi @Graham Twine

:) If you have Adaptavist script runner plugin, you can use its post function on workflow transition, name of the function is - assign to last member of the role, 

It will reassign the ticket to the person who was previous assignee from that role. 

Steps:

1. Open desired workflow in edit/draft mode.
2. Click transition on which the action is needed
3. Click Add post function
4. Click Script Post-Function
5. Click Add
6. Select Assign to last member of the role (script option)
7. Select the role (check other options if you want on this screen)
8. Click Update
9. Publish the workflow

Hope this helps :)

Regards,

Priyanka

Thanks @Priyanka Lavania

I am quite comfortable in groovy. The issue at hand is this.

The last person who was assigned to the issue is in most cases not the developer I am attempting to assign the issue to.

The person is the first person to have the issue when it enters a given state.

Hi @Graham Twine

Got it, I had similar case where the only way I could find is to store this the value in another custom filed when status changes. With complex groovy it might be possible to check issue history and get previous assignee, but we rather chose simple approach.(Explained by Thomas Schlegel  above)

For role based assignee I used Script Runner.
