Hi,

Could anyone explain how to check whether an instance is created or not for a class.

Hi,

you can check it this way...

DATA: OBJ1 TYPE REF TO YH1330_EXAMPLE.

CREATE OBJECT OBJ1.

IF OBJ1 IS INITIAL.
  WRITE 'NOT ASSIGNED'.
ELSE.
  WRITE 'ASSIGNED'.
ENDIF.

That will work, but to be absolutely clear, use the keyword "BOUND".

DATA: OBJ1 TYPE REF TO YH1330_EXAMPLE.

CREATE OBJECT OBJ1.

IF OBJ1 IS NOT BOUND.
  WRITE 'NOT ASSIGNED'.
ELSE.
  WRITE 'ASSIGNED'.
ENDIF.

Thanks Matt.... actually the keyword BOUND just went out of my mind......
