FIELD: "CLSABSTRCT" = 'X'

SELECT SINGLE @ABAP_TRUE INTO @DATA(LV_EXISTS) FROM SEOCLASSDF WHERE CLSNAME= @<print_cl>-clsname AND CLSABSTRCT = @ABAP_TRUE.

Thank you for your answer, but can you please explain more?

SE16N, paste your classname into the SEOCLASSDF-CLSNAME, observe the value of CLSABSTRCT and you will understand.

Please use the CODE button when pasting code. It makes it easier to read and you're more likely to get an answer.

    SELECT SINGLE @ABAP_TRUE INTO @DATA(LV_EXISTS) FROM SEOCLASSDF WHERE CLSNAME =  @ZMAR_HANDSON2 AND CLSABSTRCT = @ABAP_TRUE.
IF sy-subrc = 0 and lv_exists = ABAP_TRUE.
ELSE.
ENDIF.

And this is my error:

What's 'ZMAR_HANDSON2' mean? Class name or Variable name?

Re: Excluding abstract classes

omar_saber — Fri, 14 Jul 2023 09:11:05 GMT

It's a class name

Re: Excluding abstract classes

xiaosanyu — Fri, 14 Jul 2023 09:21:28 GMT

 CLSNAME = 'ZMAR_HANDSON2'

Yes the error is gone thank you, but it didn't select the class from the 3 classes which using the same interface, I use this line in this loop

'' lt_classes'' is a table which conssest the 3 classes which using the same interface and this is the error:

Re: Excluding abstract classes

xiaosanyu — Fri, 14 Jul 2023 10:02:28 GMT

LOOP AT lt_classes ASSIGNING FIELD-SYMBOL(<print_cl>).


    DATA: get TYPE REF TO zmar_if_handson .


    CREATE OBJECT get TYPE (<print_cl>-clsname).


    SELECT SINGLE @abap_true INTO @DATA(lv_exists) FROM seoclassdf WHERE clsname= @<print_cl>-clsname AND clsabstrct = @abap_true.
    IF sy-subrc = 0 AND lv_exists = abap_true.
      ls_output-daemon_name = get->naming( ).
      ls_output-priority = get->priority( ).
      ls_output-damon_config = get->get_daemon_start_config( ).
      APPEND ls_output TO lt_output.
    ENDIF.
  ENDLOOP.

You need to review the basic grammar of ABAP.

It's worse, you have removed the code!

omar.saber Better post code as text rather than image (impossible to copy/paste)
