Classification order method
          In the classification order method, products are placed into 13 classes based on turnover. The classes are divided based on percentages specified in SA Administrator Options-Products-Replenishment. Your fastest moving stock should be classified as Class 1. Your slower moving stock should be in the higher class numbers. This list shows an example based on recommended percentages: 
          
         - Class 1 Top 7.5% of products
 - Class 2 Next 7.5%
 - Class 3 Next 10%
 - Class 4 Next 10%
 - Class 5 Next 8%
 - Class 6 Next 8%
 - Class 7 Next 8%
 - Class 8 Next 8%
 - Class 9 Next 8%
 - Class 10 Next 8%
 - Class 11 Next 8%
 - Class 12 Next 9%

The products are classified according to their annual amount per warehouse. The annual amount is calculated based on the normal usage or override usage for a 12 month period times the current unit cost.
Product Administration Inventory Classification and Rank Report determines your product’s class based on the percentages specified in SA Administrator Options-Products-Replenishment. The product’s class determines the order quantity. If the product is a Class 1 product, you should purchase a one month’s supply. If the product is a Class 2 item, you should purchase a two month’s supply, and so on until you reach Class 12. You should purchase a one year’s supply.
