It can be used for various purposes. One of them, for example, is registering inquiries for their further processing and statistical purposes.
Autoincrement settings are stored in two tables:
- The Number (sys_number) table contains the Maximum digits and the Prefix settings for the table;
- The Autoincrement (sys_number_autoincrement) table stores the autoincrement setting related to the table.
| Tip |
|---|
For working correctly, records in both tables must be created. If the record in the Number (sys_number) table exists and the record in the Autoincrement (sys_number_autoincrement) table is not, then it will be created automatically, and the numbering will start with 1. |
In order to create an autoincrement rule, the following criteria must be met: the object you are configuring an autoincrement for must have a field that should be incremented. It must have a String type, and generally, these fields are named as "Number".
If your table does not have this field, please create it: please refer to the Creating a Column article for more information.1.

Autoincrement form fields
Field | Description |
|---|---|
| Maximum digits | The max amount of digits after the prefix. |
| Autoincrement | Enter the start point for the numbering. An incremental step is always 1, so further entries in this table will have the number increased by 1. |
| Prefix | At least three Latin letters that will be the beginning of every record ID in this table. |
Example
You just created the rule, and you filled in the fields:
- Maximum digits - 6
- Prefix - ABC
- Autoincrement - 123
So the first record ID will be ABC000124, and the further ones will be ABC000125, ABC000126, and so on.
