Error : 'Object does not contain an interface'

Hi Experts ,

   I have copied one standard class to custom class and within custom class GET_ACTIONS methods I am trying to access the method using below coding and getting error.

CALL METHOD super->if_powl_feeder~get_actions

EXPORTING

i_username = i_username

i_applid = lv_applid

i_type = lv_type

i_selcrit_para = i_selcrit_para

* i_langu = SY-LANGU

* IMPORTING

* e_actions_changed =

CHANGING

  c_action_defs = c_action_defs.

Please give your valuable input for reolving the same.

Thanks in advance.

What standard class have you copied?

Hi

To make it work you need to do the following:

1)  In the custom class, set the super class to CL_IBO_INBOX_FEEDER_BASE (on the Properties tab)    

2)  Redefine the GET_ACTIONS method (Second button on the right, on the Methods tab)

Now you can call the GET_ACTIONS method in the super class.  In terms of local classes, it should look something like this:

class lcl_inbox_feeder definition inheriting from cl_ibo_inbox_feeder_base.
  public section.
    methods if_powl_feeder~get_actions redefinition.
endclass.

class lcl_inbox_feeder implementation.
  method if_powl_feeder~get_actions.
    data: it_rsparams type RSPARAMS_TT,
             it_action_defs type POWL_ACTDESCR_TTY.

    call method super->if_powl_feeder~get_actions( exporting i_username = 'XYZ'
                                                                                                 i_applid = 'ABC'
                                                                                                 i_type = 'whatever'
                                                                                                 i_selcrit_para = it_rsparams
                                                                                 changing c_action_defs = it_action_defs ).
  endmethod.
endclass.

Hope that helps.
