CALL METHOD cl_hrecm00_status_change_appl=>activate_infotypes

EXPORTING

iv_orgunit = iv_orgunit

iv_test_mode = iv_test_mode

iv_note = iv_note

io_message_handler = io_message_handler

IMPORTING

ev_is_ok = ev_is_ok.

Thanks

You cannot call a protected method of a class from outside.

It can only be called in the class methods or in its subclasses.

As you know concept of OOPS..

Public Section

All of the components declared in the public section are accessible to all users of the class, and to the methods of the class and any classes that inherit from it. The public components of the class form the interface between the class and its users.

Protected Section

All of the components declared in the protected section are accessible to all methods of the class and of classes that inherit from it. Protected components form a special interface between a class and its subclasses. Since inheritance is not active in Release 4.5B, the protected section currently has the same effect as the private section.

Private Section

Components that you declare in the private section are only visible in the methods of the same class. The private components are not part of the external interface of the class.

So if you want to use it outside of class then make it public.

I am trying to make use of some of the standard sap class methods which are protected, so in that case it is not possible to reuse sap given methods in my program...

Thanks

Hi Chandra,

****All of the components declared in the protected section are accessible to all methods of the class and of classes that inherit from it.

As per this statement, if I inherit sap standard class can I access methods from protected class? Also we are on ECC6 EHP5.

Thanks

If you inherit any class , then you can access its protected property in the sub class. This is OOPS concept.

Super class..

private Section.

Method1

Protected section:

Method2.

Sub class inherited form Super class..

Now Method2 will be accessible into it...

****Its a just simple English text. Not a code..

I am trying as below to access the sap given standard class method, still not able to access , please suggest what I am doing wrong:

form perform_action

* Create a reference type for the class:

DATA: obj_cl_hrecm00 TYPE REF TO cl_hrecm00_status_change_appl.

*Create object for the referenced class

CREATE object obj_cl_hrecm00.

* Call method with object reference:

CALL METHOD obj_cl_hrecm00=>activate_infotypes

EXPORTING

iv_orgunit = iv_orgunit

iv_test_mode = iv_test_mode

iv_note = iv_note

io_message_handler = io_message_handler

IMPORTING

ev_is_ok = ev_is_ok.

endform.

Please advice what I am missing.

Thanks

Krishna

create a new class with CL_HRECM00_STATUS_CHANGE_APPL as superclass. it is not final. you will be able to call protected methods.

And btw, ACTIVATE_INFOTYPES is instnace method not static. So you call it like -> not like =>
