How can I copy value from one subtask to another subtask for the same parent

[Konica Garg]

Suppose there are 2 subtasks of a parent.
I want to copy custom field (Number field) from subtask 1 to Subtask 2

Yes, i have 3 subtasks.
I want to copy value from Subtask 1 and Subtask 2 and put the value in Subtask 3
I am using branch condition but it is not working for subtasks.

Hello @Konica Garg 

You can accomplish that with an Automation Rule.

Do you have more than two subtasks under the same parent?

If so, how do you identify the subtask that has the value you want to copy, and the subtask to which you want to copy it?

What issue event should trigger copying the value? Should it be copied only when the source subtask is created? Should it be copied when the value is changed in the source subtask?

What if the destination subtask already has a value? Should it be overwritten?

You can find documentation for the Automation feature at the link below. You should make an attempt at creating the rule, and ask us more questions if you need more help.

Please show us the complete Automation rule you have, and the Audit Log details for a time when it executed and did not do what you wanted.
