This function calculates the ratio between two source POVs (C = A / B).
As a best practice, it is recommended that variables are set in the calling routine and passed to the Pro_Rata_Ratio function, which define the Destination, SourceN and SourceD POVs. It is also recommended that the variable names in the calling routine be set to be the same as the Pro_Rata_Ratio function.
The system does not naturally calculate weighted average ratios for parent members. Parent member values display as an aggregation of child values. This results in a mathematically incorrect value for parent members. As such, it is recommended that aggregation be turned off for Ratio accounts.
