Purchase Price Variances model
The purpose of this model is to analyze the variances in purchase prices when making these main comparisons:
- Monitor purchase order variances measured as the variance between standard
        costs and the cost-values of the purchase order when goods are being received
Monitor purchase invoice variances measured as the variance between costs captured at goods receipt and the invoice costs
 
The solution provides analysis from various dimensions, such as suppliers, buyers, material, and calendar.
