Jira automation- set time remaining to 0 when closing a subtask

[yinon.eitan]

Hey, 

there is some way to set up a rule in the Jira automation that will change the time remaining to 0 when closing a subtask? 

I tried a rule like: 

When: issue transition to 'closed' then edit issue fields Original Estimate/Remaining Estimate to 0

and advanced setting like - 

{
"fields": {
"timetracking": {
"originalEstimate": "10m"
}
}
}

But it didn't work and got this error

EDIT ISSUE
Unknown fields set during edit, they may be unavailable for the project/type. Check your custom field configuration. Fields ignored -
Time tracking (timetracking)
No fields or field values to edit for issues (could be due to some field values not existing in a given project):
AT-9999

Thanks in advance

Hello, 

Is there a specific reason you want to use automation instead of a postfunction?

I think you should consider looking into adding a postfunction in the closing transition that set the field value to want you want!  

Give it a try a give us some news!

Hey 

Thank you for your answer, I wasn't familiar with post-function in the workflows, but I did give it a try and it worked so thanks for that. 

Correct me if I'm wrong' but adding a post-function to the workflow will affect every project that uses this workflow no?

I don't want to affect other projects and it would be nice to know how to do it in the automation rules anyway.

Thanks again
