Overview of Sequential Number Ranges in SAP

In SAP (Systems, Applications, and Products in Data Processing), sequential number ranges are essential for organizing and managing various types of data, including documents, invoices, and transaction records. These ranges ensure the uniqueness and validity of key identifiers within the system, thereby supporting data integrity and operational efficiency.

Sequential number ranges are predefined intervals of numbers that are used to generate unique identifiers for various business documents and processes within SAP. These include document numbers for invoices, purchase orders, sales orders, and delivery notes.

The primary purpose of sequential number ranges is to avoid duplication of numbers, ensuring each document can be uniquely identified. This helps in both data retrieval and auditing processes.

Types of Number Ranges

• Internal Number Range: SAP automatically assigns numbers within a specified range when a document is created. The system controls the assignment to ensure no two documents receive the same number.
• External Number Range: Users manually assign numbers from an external source. This is often used in cases where businesses have specific numbering systems or formats in place.
