1.Functional Description
1.1Purpose
This function will generate the forecast numbers for Method 8, Percent Over N Months Prior, if the 
processing option is set to do so.  It will also decide if this method is the Best Fit forecast.
1.2Setup Notes and Prerequisites
1.3Special Logic
2.Technical Specifications
Method 8- Simulate Flexible Method
 If NumberOfBuckets is less than MonthsBestFit + NumberMonthsPrior
 Move '1' to DataError
 End Function
 End
 If MeanAbsoluteDeviation is not equal to '1'
 Subtract (MonthsBestFit + NumberMonthsPrior - 1) from 
LastBucketPosition to get $X
 Do MonthsBestFit times
 If ForecastAmounts is not set to '1'
 Add PtrToActualSales,$X to FlexibleTotal
 Else
 Add PtrToActualAmounts,$X to FlexibleTotal
 End
 Subtract 1 from $X
 End
 Multiply FlexibleTotal by FlexiblePercent to get $$SIM
 If ForecastAmounts is not equal to '1'
 Divide $$SIM by QtyBestFit to get MethodYield
 Else
 Divide $$SIM by AmtBestFit to get MethodYield
 End
 Decide if this method is the Best Fit Method
 If MethodYield is greater than 1
 Subtract 1 from MethodYield to get $SPER
 Else
 Subtract MethodYield from 1 to get $SPER
 End
 If $SPER is less than BestFit
 Move $SPER to BestFit
 Move 8 to Method
 End
 Else
 Subtract (MonthsBestFit - 1) from LastBucketPosition to get $X
 Subtract NumberMonthsPrior from $X to get $Y
 Move zeroes to $TOT
 Do MonthsBestFit times incrementing $X and $Y
 If ForecastAmounts is not set to '1'
 Multiply PtrToActualSales,$Y by FlexiblePercent to get 
$$SIM
 Subtract $$SIM from PtrToActualSales,$X to get $DIFF
 Else
 Multiply PtrToActualAmounts,$Y by FlexiblePercent to get 
$$SIM
 Subtract $$SIM from PtrToActualAmounts,$X to get $DIFF
 End
 Add the absolute value of $DIFF to $TOT
 End
 Divide $TOT by MonthsBestFit to get MethodYield
 Decide if this method is the Best Fit Method
 If MethodYield is less than BestFit
 Move MethodYield to BestFit
 Move 8 to Method
