# Number Server

## Introduction

| The number server generates unique IDs for data objects such as items and documents. The number server function allows for a flexible definition of enumeration ranges in conjunction with a complex enumeration syntax. The number server is called up from the Manager menu: Manager > Tools > Number Server. A combined mask is displayed where you can enter all parameters required for the definition of enumeration variants. Enumeration variants can be divided into different ranges, so as to make sure that enumeration digits (e.g. "12345") can be combined with text strings (e.g. "BE12345"). The number server assigns IDs in ascending order or in descending order if a negative stepping has been defined. If IDs are deleted (e.g. by removing a master record) they cannot be replaced by the number server, i.e. this ID will be missing in the enumeration range. Users may define an "Alarm Number". The system will send will send you a warning message informing you that the enumeration range is about to be filled once this ID is reached. The system administrator will therefore know in time when to define a new enumeration range.
