Have a question on how to calculate a suppliers ppm for the Year To Date calculation.
We report the monthly ppm rating of our suppliers and have a few individuals argument on how to calculate a YTD figure for them.
Is there an exact method on how to do this? Do you just simply add each months ppm of that supplier and divide by the number of months reported?
Appreciate help and comments to this.
