• Key Concepts: 
  A Stock Management Unit (SMU) is a unit of measure used in SAP Inventory Management (MM-IM) to define the quantity of an item in stock. It is used to track the quantity of an item in a warehouse or other storage location. The SMU is defined by the user and can be any unit of measure, such as pieces, boxes, or pallets. 
  
  How to use it: 
  In SAP Inventory Management, the SMU is used to track the quantity of an item in a warehouse or other storage location. When creating a material master record, the user can define the SMU for that material. The SMU will then be used to track the quantity of that material in stock. The SMU can also be used to define the minimum order quantity for a material. 
  
  Tips & Tricks: 
  When defining an SMU for a material, it is important to choose a unit of measure that is easy to understand and use. For example, if you are tracking items in boxes, it may be easier to use “boxes” as the SMU rather than “pieces” or “pallets”.
