Payroll OTBI with Balance Definitions, Names, Feeds and Element names with Input Value Names

Summary

We have a Balance Name called Net Pay with a Balance feed of multiple combinations of Elements and Input Value Names but I cannot find this relationship in the many Payroll OTBI Subject areas

Good evening all, 

This is my first post to Cloud Customer Connect. I've worked a year using Oracle on mainly HCM but I've only recently started reporting on Payroll data. So any help would be very much appreciated. 

I'm trying to report on Net Pay using OTBI and the Payroll - Payroll Run Results Real Time subject area. 

I can easily output the Element Name and Input Value Names per person per pay period. But now I just want to report on combinations that contribute to Net Pay.
