Thank u for your response but it doesn't work.

the problem is here:


if lv_vbap eq CL_RETM_PERIOD_MNGR.

It takes CL_RETM_PERIOD_MNGR as a field and not as class, and gives: CL_RETM_PERIOD_MNGR is unknown

I meant to check the instance of the class....

You mean: ?


        IF lo_specific_term_mngr  EQ {O:153*\CLASS=CL_REAJ_TERM_MNGR}.

          DO.
            go_adjmterm_mngr ?= lo_specific_term_mngr.
          ENDDO.
        ENDIF.

If it's that , it doesn't work: the error message: {0 is unknown.

Hello

Perhaps for this requirement SAP provides a corresponding method:


*&---------------------------------------------------------------------*
*& Report  ZUS_SDN_IS_INSTANCE_OF
*&
*&---------------------------------------------------------------------*
*& Thread: Problem with Abap Object 
*& <a class="jive_macro jive_macro_thread" href="" __jive_macro_name="thread" modifiedtitle="true" __default_attr="1309987"></a> 
*&---------------------------------------------------------------------*

REPORT  zus_sdn_is_instance_of.


DATA:
  go_term_mngr      TYPE REF TO cl_reaj_term_mngr,
  to_period_mngr    TYPE REF TO cl_retm_period_mngr.


START-OF-SELECTION.

" NOTE: Direct instantiation not possible => fake coding
  CREATE OBJECT go_term_mngr.
  CREATE OBJECT go_period_mngr.

  IF ( cf_reca_object=>get_classname( go_term_mngr ) = 'CL_REAJ_TERM_MNGR' ).

  ELSE.

  ENDIF.


END-OF-SELECTION.

Perhaps it is necessary to use the underlying interfaces instead of the classes:

IF_REAJ_TERM_MNGR
IF_RETM_PERIOD_MNGR
