Rehaman,

it is possible to access the methods defined in one class by methods in another class by using inheritance.

class my_class1 DEFINITION.

PUBLIC SECTION.

methods: m1.

endclass.

class my_class1 IMPLEMENTATION.

method: m1.

write:/ 'This is m1 method'.

endmethod.

endclass.

class my_class2 DEFINITION INHERITING FROM my_class1.

PUBLIC SECTION.

methods: m2.

endclass.

class my_class2 IMPLEMENTATION.

method: m2.

write:/ 'This is from method m2'.

endmethod.

endclass.

data: obj_ref2 type ref to my_classs2.

start-of-selection.

create OBJECT obj_ref2.

*To call method m1 of my_class1.

call method obj_ref2->m1.

*To call method m2 of my_class2.

call method obj_ref2->m2.

if useful, reward points.

Thanks you,

Hi checkout this sample code.....any clarrification..really appreciated.

class lcl_a  DEFINITION.
  PUBLIC SECTION.
  methods: m1.
endclass.

class lcl_a IMPLEMENTATION.
  method: m1.
    write:/ 'I am method of A class'.
  endmethod.
endclass.

class lcl_b DEFINITION INHERITING FROM lcl_a.
  PUBLIC SECTION.
  methods: m2.
endclass.

class lcl_b IMPLEMENTATION.
  method: m2.
write:/ 'I am method of B Class'.
 endmethod.
endclass.

 data: o_refb type ref to lcl_b.

 start-of-SELECTION.

 create OBJECT o_refb.
*You are calling A Class method M1.
 call method  o_refb->M1.
*You are calling B Class method M2.
 call method  o_refb->m2.

In a method in class B

* M1 static
CALL METHOD A=>M1 EXPORTING... IMPORTING...
" or
A=>M1( parameters ).

* M1 not static
" Create instance of A
DATA: lo_a TYPE REF TO A.
CREATE OBJECT lo_a EXPORTING...

CALL METHOD A->M1 EXPORTING... IMPORTING
" or
A->M1( parameters ).

Simple, isn't it.
