change the value of the start date of a task

Fotios Liachas

I try to create an automation, which will adjust the start date of a task to the min date of its sub-tasks.

the strange think is, that it is not possible to 'read' the value(s) of the start date(s) in sub-tasks I made the 'opposite' rule (adjust due date of a task to the max date of its sub-tasks) and works perfect any idea?

the basic structure of the trigger/rule is:

When: Value changes for : start date

Issue Type equals: sub-task

for: Parent Edit Issue fields: start date (={{issue.subtasks.startdate.max}})

Hello @Fotios Liachas 

Welcome to the community. 

What is the result that you are getting in this case? Can you show us the rule execution log output?

You said you want the min date from the subtask Start date field, but your smart value uses "max". That could be one problem.

Another problem could be that field names in smart values are case and spacing sensitive. What is the exact, visible name for your start date field? Is it...
startdate
Start Date
Start date

How you specify it in the smart value needs to match how you see it in the issue screen. If you don't specify it correctly the Automation rule will simply say there is no value to use.
