Overview  

Im many data structures, you must be able to access database records individually. You do so by using unique keys. Number ranges assign numbers to complete the keys of the individual database records of a business object. Such numbers are, for example, order or material master record numbers.

These numbers encode differentiating information about the object, as well as uniquely identifying data records. The number indicates, for example, the type of a material.

The number range management also ensures that numbers are only assigned once.

All dialogs, database accesses or other number range object and number range maintenance tasks, and customer development number assignment, can be performed by SAP function modules.
