** Concept **

A **number range object**
contains all the definitions which are needed for the number
assignment for a commercial object. One or more number ranges can
be assigned to a number range object.

A set of characters or numbers is defined in the **number
range**. A number range can be:

**external**

The numbers are assigned manually by the user.

**internal**

The numbers are assigned automatically by the system.

The number range is identified in the system by the number range number.

The character set in the number range is determined by the
**number range interval**. It consists of numbers or
alpha-numeric characters, and is delimited by the fields
*from-number* and *to-number*.
