to be clear here, Links do not work that way. That is, Links do not establish a parent-child relations ship. At least not in the way a Task > Sub-task does. With that said, as Flavien offered, you can use Automation to achieve your goal (maybe). Basically something like this...
Trigger = issue updated
Condition = use a JQL like issueLinkType is not Empty
Condition = something else to ensure you are don't execute the following actions when not desired
Action = update the linked issue as you need
You need to use the automation module in Jira cloud. It allows you to create a rule that will trigger when an event occurs.
For example you can change the status of your parent ticket to "In progress" if one of your subtask changes to "in progress".
You also can make a rule to close a parent ticket if all the subtask are closed.
We often have questions from folks using Jira Service Management about the benefits to using Premium. Check out this video to learn how you can unlock even more value in our Premium plan. &nb...
