According to the Oracle SCM Business Process Certified Foundations Associate Rel 2 document1, the purpose of defining the ABC Classification is to decide the frequency to perform inventory accuracy review. ABC Classification is a method of categorizing inventory items based on their value and usage. Items are classified into three groups: A, B, and C. A items are the most valuable and frequently used items, B items are moderately valuable and used items, and C items are the least valuable and rarely used items. The ABC Classification helps to prioritize the inventory management activities, such as cycle counting, physical counting, replenishment, etc.
