Go and Create 

In the following sections, you will learn how you can easily use the ABAP Dictionary to create a table in the database and a system-wide class that manages this data.

You create the database table with its fields and the desired attributes via metadata in the ABAP Dictionary. When you activate the object, the table is created on the database. The field types created in the ABAP Dictionary are then available system-wide. You can access them from your ABAP program if you use ABAP Objects to program corresponding service methods for accessing the table.
