• Key Concepts: 
  Number range buffer is a component of the SAP Client/Server Technology (BC-CST) that stores and manages number ranges. It is used to assign unique numbers to documents, such as invoices, orders, and delivery notes. The number range buffer ensures that no two documents have the same number. 
  
  How to use it: 
  The number range buffer is used to assign unique numbers to documents. It can be accessed through the SAP transaction code SNRO (Number Range Object Maintenance). This code allows users to create, change, and delete number ranges. The number range buffer also allows users to define the length of the numbers and the interval between them. 
  
  Tips & Tricks: 
  When creating a new number range, it is important to make sure that the interval between numbers is large enough to accommodate future documents. This will help prevent duplicate numbers from being assigned. Additionally, it is important to make sure that the length of the numbers is appropriate for the document type.
