PRIVATE SECTION.
You can only use this statement in the declaration part
of a classe in ABAP Objects. It opens the
private section of the class definition, which ends at the ENDCLASS statement.
The private section is one of the visibility sections of a class, which define the external visibility of the components of the class.
A class definition need not contain a private section. However, if it does, the private section must be the last visibility section to be defined (after the public and protected sections).
All of the components of the private section can access the components of the public and private sections.
