Turns start date equals due date in differents subtasks

[Douglas Oliveira]

Hi,

How do i turn star date of a subtask to be the same of the due date of another subtask?

Note:  I have some subtask with differents names.

Hi @Douglas Oliveira 

What is the relationship in Jira between these sub-tasks?  For example, do they have the same parent, are the linked, etc.?

• If this is a one-time change, and these are two unrelated sub-tasks, you could directly edit those fields using the UI
• If instead you need this change/edit often and there is a relationship that can be determined from the issue fields, you could use automation rules to make the change

Kind regards,
Bill

Hi @Bill Sheboy , Thanks for feedback.

They have the same parent, and i want wich the rule repeats ever.

I tried use the automation but the function wich i used not work it.

i used: {{Subtask1.startDate.isEquals(Subtask2.dueDate)}}.

Hi @Douglas Oliveira 

You cannot reference the sub-tasks as you have noted in smart values; each is its own issue, and I expect you will need to use some branching and/or created variables to do this in a condition.

Please post an image of your rule as that will provide some context for the community to offer more specific suggestions.  Thanks!

Hi @Bill Sheboy , folow the picture 

Note: Cadastro and Produção are Subtasks

[Bill Sheboy]

Thanks for that information!

Okay, the isEquals() function returns true or false, and not a date.  The key here is how to find the sub-task that you want to update and to give that a date field.  Let's assume there is one-and-only-one Produção sub-task with the same parent as the Cadastro sub-task.

If so, it seems like what you are asking to do is this:

• trigger: due date changes value
• condition: issue type is Cadastro (which you note is a sub-task type)
• branch: on JQL to return the sub-task to update

parent = {{triggerIssue.parent}} AND issueType = "Produção" 

• action: edit issue to set the Start Date to {{triggerIssue.duedate}}

Please check/confirm your issue type spelling as I was copying from our posts.

Exactly, they have the same parent and i want wich the "Produção" start date are the same "Cadastro" due date always. If i to change one, will change the other.

[Bill Sheboy]

Yes, I understand.  Then you will need 2 rules to keep these fields in synchronization:

• The rule I provided above, and
• A second and opposite rule, which detects a change to Start Date in one sub-task in order to update the Due Date in the other.  You should be able to create that by copying and adjusting the first rule.

Please note: because these two rules could create a "dead-lock" situation by altering the same fields, you will want to alter the triggers so they only fire for "edit issue" and you will want to add a condition after the trigger that the edit was not done by automation:

• user condition: user  "Who triggered the event" is not the "Automation for Jira" user

Nice!

Only the first rule work it good and did wich i wanted.
Using the JQL branch and the correct trigger the rule worked good.

Thanks @Bill Sheboy !
