You will learn how to create a table type object in the ABAP dictionary, this can be re-used in different programs to declare table type variables.

Table Types

Table types are construction blueprints for internal tables that are stored in the ABAP Dictionary.
When you create a table type in the ABAP Dictionary, you specify the line type, access type, and key.
The line type can be any data type from the ABAP Dictionary, that is, a data element, a structure, a table type, or the type of a database table
In an ABAP program, you can use the TYPE addition to refer directly to a table type. ->

Visibility of Global and Local Data Objects

Variables defined in the main program are global data objects.
They are visible (can be addressed) in the entire main program in every subroutine called.
Variables defined within a subroutine are called local, as they only exist in the relevant subroutine - just like the formal parameters.
The formal parameters and local data objects of a subroutine can not have the same names.
