输入任意类型对应的ID，该report能打印出ID对应的object type:

REPORT zdisplay_id.

PARAMETERS: id TYPE if_fdt_types=>id OBLIGATORY DEFAULT 'FA163E8EAB031EE48B847ADC6A96D5F0'.

START-OF-SELECTION.

 DATA:      lo_instance TYPE REF TO if_fdt_admin_data,

            lv_unknown  TYPE boolean.

 CALL METHOD cl_fdt_factory=>get_instance_generic

   EXPORTING

     iv_id         = id

   IMPORTING

     eo_instance   = lo_instance

     ev_id_unknown = lv_unknown.

 IF lv_unknown = abap_true.

   WRITE: / 'ID Unknown.' COLOR COL_NEGATIVE.

   RETURN.

 ENDIF.

 DATA(lo_object) = cl_abap_classdescr=>describe_by_object_ref( lo_instance ).

 WRITE: / lo_object->get_relative_name( ) COLOR COL_NEGATIVE.

输出CL_FDT_FUNCTION, 表明该ID对应的object是 Function

输出CL_FDT_RULESET, 表明该ID对应的object是Ruleset
