Automate the start and Due date of a task in the timeline

[Mohammad Eltrissi]

Hi All, 

It might be a fundamental question, but I am try to reach the solution without success. I am using Jira cloud software, and I want to auto-update tasks' start and due dates like any other Project management application. 

IF task A has a start and due date.

and task B is connected to task A in relation of start B after end A

How can I automate Jira to change task B's start and due date if Task A (the linked and dependent) is changed?

Hi Mohammad - Welcome to the Atlassian Community!

What are the actual field names you are using? 

You should be able to create an Automation Rule that will do what you want. Basically a Field Value Changed trigger on the End Date. Add any needed Conditions.

Then add a Branch for Linked issues. Select the particular issue type if relevant.

Add an action for Edit Issue and select the start date. Then you can make it = to the end date of the trigger issue or end date + 1 or something like that. 

Give it a shot and then post your rule here if you need further assistance.
