Increase value of field per task

[Kristian Partl]

Hello,
I am looking for solution which will solve my problem.
I got a numeric field, this field represents invoice number.
And when someone creates new task, I want to automatically set this field on higher number than it was before on previous task.

Does someone ever did something similar, is it possible?

Thanks.

Hi Kristian,

Create an automaiton rule for an Issue Created Trigger

Add a Condition for Issue Type = Task (and any other conditions needed)

Then add an action for Edit Issue, and select the Invoice Number field. 

Then put this in the blank box under the field: {{#increment}}{{issue.Invoice Number}}{{/}}

where Invoice Number is the EXACT NAME of your custom field - adjust as needed in the text above so it matches your field name.
