SAP Quick Sizing

When you are in the quick sizer, there are elements that are listed in the tool by functional area. The question I have is, a way to use the element to find out what SAP tables are tied to these elements in SAP. I am dealing with gathering data in existing SAP instance to bench mark the volume information. Is there a way to see what SAP tables are tied to the elements in quick sizer tool? Where and how can I see them?

Thanks
