In Designer mode

Attention! Since during the previous lesson you created a list of users in the configuration when you start Designer you are prompted for a user name. Enter Administrator as the user name because this user has full access to all the configuration objects. There is no need to enter a password because you have not created one.

The Constant configuration object is used to create database tables for storing data that is never changed over time or is rarely changed.

Each Constant configuration object defines a table that stores a single value.

Let us proceed to creating a constant for storing the number prefix value.

1. Open Designer and create a Constant configuration object named NumberingPrefix.
2. Set its data type to String with a fixed length of 2 characters.
