Convert perform subroutine into method using oops concepts in SAP ABAP.

Greetings Abapers,

Need to translate-procedural subroutine call using internal table into method call using oops concepts.

Sample statement -

PERFORM f_test_subroutine TABLE lt_table .

------------------------------------------------------------------------

FORM f_test_subroutine TABLES tab1 like gt_test.

ENDFORM.

------------------------------------------------------------------------

Please provide definition and implementation of class as well.

Thanks in advance 🙂

Seems quite basic, what is your problem rewriting form as method?

Chat gpt can answer this kind of question reasonably well.

Usually methods don't support TABLES parameters.

So wanted to know how exactly we translate the same.

It's not "usually", "TABLES" parameter has been obsolete for a long time (at same time as subroutines I guess), and doesn't exist in methods. You pass internal tables by declaring a Table Type, and using it via IMPORTING, EXPORTING, CHANGING or RETURNING/RECEIVING.

TYPES your_type_name TYPE ... TABLE OF ... (could be also a range type or a DDIC Table Type instead of TABLE OF)

METHODS ...

parameter_name TYPE your_type_name
