We have a Jira Service Management Project A which collect customer tickets. If we cannot resolve a ticket in Project A, we escalate by creating a ticket in Jira Software Project B, then link both tickets together.
We would like to create a report on "Number of tickets in Project A got escalated to Project B in a month". This seems cannot be done by default. It seems some plug in Apps can report on linked issues, but I am not sure if they can create summary on total count of linked issue as we need.
I will be appreciated if you can point me to the right direction or give me some idea. Thanks.
