Hi Varun Shukla

Here's about the pattern: https://en.wikipedia.org/wiki/Factory_method_pattern

Here's an example for ABAP: https://blogs.sap.com/2012/02/20/factory-pattern-in-abap-oo/

The example is complex, with configuration based on DB table, but it can also be as simple as

METHOD create_instance.
  IF iv_value = 'A'.
    CREATE OBJECT ro_instance TYPE lcl_a.
  ELSE.
    CREATE OBJECT ro_instance TYPE lcl_default.
  ENDIF.
ENDMETHOD.

Kind regards,

Mateusz

Hello Varun Shukla,

The factory method is most used for creating objects without any leverage to its instantiation technique. Interfaces and encapsulation concepts of OOABAP plays a vital role here.

You can follow the blog below which discusses the method in detail.
