If a method uses private components of the class, and this method is not redefined and being called from a subclass, it will always use the private components of the superclass, even if the subclass has its own private components of the same name.
Code:
REPORT ZVV0002.
*----------------------------------------------------------------------*
class c_base definition.
public section.
methods: constructor importing value(p_name) type string,
m_show1,
m_show2.
private section.
data a_name type string.
endclass.
*----------------------------------------------------------------------*
class c_derived definition inheriting from c_base.
public section.
methods: constructor importing value(p_name1) type string
value(p_name2) type string,
m_show1 redefinition.
private section.
data a_name type string.
endclass.
*----------------------------------------------------------------------*
class c_base implementation.
method constructor.
a_name = p_name.
endmethod.
method m_show1.
write: / 'Show1 :', a_name.
endmethod.
method m_show2.
write: / 'Show2 :', a_name.
endmethod.
endclass.
*----------------------------------------------------------------------*
class c_derived implementation.
method constructor.
call method: super->constructor exporting p_name = p_name1.
a_name = p_name2.
endmethod.
method m_show1.
write: / 'Show1_r:', a_name.
endmethod.
endclass.
*----------------------------------------------------------------------*
data o type ref to c_derived.
*----------------------------------------------------------------------*
END-OF-SELECTION.
*----------------------------------------------------------------------*
create object o exporting p_name1 = 'Base...' p_name2 = 'Derived...'.
call method: o->m_show1,
o->m_show2.
*----------------------------------------------------------------------*
