Creating report that depends on open issues in one project that have issues in another project

[Deleted user]

I have one project that is for client implementations and another that has issues to be resolved.  I am trying to create a query to find issues in the second project that have the same client as the first project. 

So if Client 123 is in project one and has an open status and Client 123 has an open issue on the second project, I want to report info from the second project.

I tried "project in ("project1", "project2") AND status != Done AND "Reporting Partner(s)" is not EMPTY ", but it's not quite right.  It pulls in issues from both projects and I don't know how to make the query based on one with data from the second.

Is it even possible?  

Thank you for any help that you can provide!

Thank you, @Muhammad Ramzan(Atlassian Certified Master)  I appreciate the fast response.  Unfortunately, buying another tool isn't an option.

You can easily find such results by using plugin JQL Search Extensions for Jira & reports

Following query will fetch all issues where  reporting partner from project 1 and project 2 are matched.

issue in fieldsHaveSameValue("reporting partner in project1", "reporting partner in project2")

or you can use following query

issue in fieldMatch("project in(project1,project2)", "Reporting Partner(s)", "create the regular  expression")

you can find the documentation here for any clarification
