How to update different project's link issue state？

[諶玟萁 Elly Shen]

here is the scenario：

A project task issue link to B  project task issue.
when A   task issue state change to in progress than B  project task issue can be update to the same state.

if a and b has different workflow,is that possible to use JQL to show about this scenario?

If can use JQL to show about this scenario,how can i do?

I believe that in this case you don't need to use exactly a JQL, but rather use global automation and insert a branch to read related issues between projects A and B;

Here's an example of an automation framework that could be useful to you in this process:

Whenever an issue transitions to "Refinement";
If it is from the SUB project

The branch will read issues from any project linked to the SUB issue via the "reports to" link type and will transition these related issues to "In progress"

I hope this helps. If you have any question, let me know.
