Re: Acessing of private method in public method within same class

For sure you can access private variables/methods within the public method of the same class. Usually the variables should all be defined private and then use corresponding getter and setter to access them...

Some example:

*----------------------------------------------------------------------*
*       class lcl_class definition
*----------------------------------------------------------------------*
*
*----------------------------------------------------------------------*
CLASS lcl_class DEFINITION.
  PUBLIC SECTION.
    METHODS: sub, get_j EXPORTING j TYPE i.

  PRIVATE SECTION.
    DATA: i TYPE i,
          j TYPE i.
    CLASS-DATA:k TYPE i VALUE 5.
    METHODS:  add.

ENDCLASS.                    "lcl_class DEFINITION

*----------------------------------------------------------------------*
*       class lcl_class implementation
*----------------------------------------------------------------------*
*
*----------------------------------------------------------------------*
CLASS lcl_class IMPLEMENTATION.
METHOD add.
    DATA l TYPE i.
    me->l = 20.
    me->i = 10.
    me->j = 30.
    me->k = me->i + me->j.
  ENDMETHOD.                    "add

  METHOD sub.
*    data obj type ref to lcl_class.
    call method me->add.
    me->i = 10.
    me->j = 20.
    k = me->i - me->j .
  ENDMETHOD.                    "sub

  METHOD get_j.
    j = ME->J.
  ENDMETHOD.                    "get_j
ENDCLASS.                  "lcl_class IMPLEMENTATION

START-OF-SELECTION.
  DATA obj TYPE REF TO lcl_class.
  DATA: lv_j TYPE i.

  CREATE OBJECT obj.
  CALL METHOD obj->sub.
  CALL METHOD obj->get_j
    IMPORTING
      j = lv_j.

  WRITE: lv_j.
