Excluding abstract classes

[omar_saber]

Hello everyone,

I have one interface which is used for 3 classes and I have one class from this classes is Abstract class I need a way to to exclude this class when I call the program, please find my code here:

[xiaosanyu]

TABLE: "SEOCLASSDF"
FIELD: "CLSABSTRCT" = 'X'

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.
" ABSTRCT CLASS
ELSE.
ENDIF.

[omar_saber]

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

[xiaosanyu]

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

[omar_saber]

I Understand now but when i pass my class name into CLSNAME = @myclass_name I get an error says that this field is uknown IDK why, do you have why is this happening?

[xiaosanyu]

Please provide a screenshot of the error & paste your code.

[omar_saber]

    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:

[xiaosanyu]

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

[omar_saber]

It's a class name

[xiaosanyu]

 CLSNAME = 'ZMAR_HANDSON2'

[omar_saber]

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:

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

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

I added, thank you for letting me know 🙂

[xiaosanyu]

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.

[omar_saber]

I am a beginner to ABAP programming and have only been started 3 weeks ago so I still learning, But thank you very much for your help, I am really appreciate it 🙂

[xiaosanyu]

Cheer. 💪

It's worse, you have removed the code!
