Unable to find FPS Column to Balance Definition Mapping

Summary: I need to adjust several FPS columns, but we are unable to find any mapping documentation in the Oracle Community, Oracle Support Portal, or official Oracle documentation.
There are 53 FPS columns that report figures/amounts derived from Payroll Balances. We need to modify these values; however, we cannot locate a definitive source that specifies which payroll balance definition corresponds to each FPS column. While we have successfully mapped many of them, some FPS column names do not clearly match any balance definition.
Can anyone provide documentation that explicitly identifies which balance definition is used for each FPS column. This will enable us to make the necessary adjustments and ensure the FPS report reflects the correct values.
