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
End
End
