How to automatically assign a user to a subtask

How do I automatically assign a user to an existing subtask?

Hi @Angela DiCesare

By default, your sub tasks will be assigned to the component lead. If one of your sub tasks should go to a different user, you can hard code this change in the post function.

NOTE: This solution utilizes script runner add-on to hard code the assignee to the sub task.

1. Go to your project
2. Click Project Settings
3. Click Workflow
4. Edit your workflow
5. Choose diagram
6. Click the first transition (create), then click Post Functions
7. Click Script Post-Funciton [ScriptRunner]
8. Create sub task
9. Condition = the script for identifying the component:
   
   import com.atlassian.jira.bc.project.component.ProjectComponent
   import com.atlassian.jira.component.ComponentAccessor
   
   for(ProjectComponent projectComponent: issue.getComponentObjects()){
   if(projectComponent.getName().equals("COMPONENT NAME"))
   return true
   }
   return false
   
   
10. Target Issue Type = Sub-task
11. Sub Task Summary = What the sub task will be called
12. Additional issue actions field:
    
    issue.assigneeId = "TYPE USER NAME HERE"
    
    
13. Click Update
14. Publish the workflow changes

Hope this helps or at least gets you past 1 hurdle!

on Step 6, I cannot see "Post Functions" when I click the first transition (create), or in fact any transitions, and actually I cannot see anything popping up when hoving over or right-clicking on them. It could be any permissions constraints?

The new answer now is utilize Jira Automation.

   I updated the response above.

My setup is to generate a sub task based on selection of a component. The sub task will then auto assign to whoever we hard code in step 12.

It is messy but it works.

Ok, thanks!

Hi, I would like to do the same automatic assignment but I can't find the "Additional issue action" field on the "Post function" list.

Can you give me any suggestions?

Thanks
