I am trying to set up the Due Date via automation to 2 weeks or 14 days prior to another custom date field. I google and found: {{triggerissue.customfield_10072.minus(14)}} but that didn't work.
The value for the custom date field is from another ticket which is linked to the ticket that I am trying to update.
So basically. I am trying to set the Due Date as CustomDateField - 14.
Can there be a smart value for the jira automation for this?
