Help creating relationship between catalog item reference variable and ServiceNow Catalog items

[Classic]

Hello, I have a catalog item that's used to take requests for modifications to other catalog items it's called the ServiceNow Enhancement request. In this ServiceNow Enhancement request there is a reference variable that is used to select which catalog item needs to be modified. I want to create a relationship that lists all the requests from the ServiceNow Enhancement request with the catalog items corresponding to the reference variable. As an example if I pulled up a catalog item "X" and hit configure item I want a tab to show all the requests that were put in through ServiceNow Enhancements for catalog item "X". I was able to create a tab called Related Catalog Items by creating a dictionary entry as shown in the screenshots but I'm not sure how to populate the table. 

Thanks in advance for any pointers!

Why don't use reporting to satisfy your requirement? What is the business case of showing all the request made for catalog Item X on another catalog Item?

Hey thanks for your reply. It's so that a developer can see what work has been/is being done on the catalog item when they're working on it. Reporting didn't satisfy the requirement.

Hello thanks for the response, reporting does not satisfy the requirements.
