Updated 'Linked Issues' field value to link an issue in another project

[Shahzad Anwar]

I have two project A & B having a common field 'DRN'.

In Project A, if any an issue's DRN field is added/edited, it should look for DRN field entry in Project B. If found, then related issue of Project B should link automatically to Project A ''Linked Issue' field.

Thus, we'll be able to track from Project A issue, any related issue if exists in Project B based on common DRN filed entry.

Hello @Shahzad Anwar 

Welcome to the Atlassian community.

You can accomplish this using the Automation for Jira feature.

This would require a multiple project rule, and such rules can be created only by Jira Administrators. Are you a Jira Administrator, or can you engage such a person to help you?
