The function modules in this group manage the number assignment.

• NUMBER_CHECK
  You only need this function module for external number assignment. It checks whether a number range object number lies in a specified number range interval.

• NUMBER_GET_INFO
  This function module gets information for a specified number range object number range interval.

• NUMBER_GET_NEXT
  You need this function module for internal number assignment. It assigns the next free number(s) in a number range interval of a specified number range object. If the last number in the interval has been issued, the number assignment begins again with the first number in the interval.
  The return code states whether the assigned number was assigned without any problem, or whether it lies in the critical range.
