Error when calling a method inside a form routine...

Hello experts,

I am trying to call a method inside a form but it is giving me an error. The error is:

Access not possible using 'NULL' object reference.

Anyway, below is my code guys:

START-OF-SELECTION.

DATA: main TYPE REF TO lcl_main,

old_and_new TYPE REF TO lcl_old_and_new,

check_changes TYPE REF TO lcl_check_changes,

messages TYPE REF TO lcl_messages.

CREATE OBJECT: main, old_and_new, check_changes, messages.

----

----

----

FORM get_orig_contents_of_zts0001.

CALL METHOD main->export_old_recs.

ENDFORM.

Help would be greatly appreciated. Thanks a lot and take care!

Hi Viray,

Loks like ur method is not avaliable for the subroutine u r calling.

Just check whether u have defined the method and all it's objects in ur program.

Cheers,

hi,

While calling a method it should be available. You need to define the class and its methods in the program. You might have missed some method.

Before the "START-OF-SELECTION " just add this sentense :

<b>class lcl_main definition deferred.</b>

CLASS Definition.

ENDCLASS.

CLASS Implementation.

ENDCLASS.

START-OF-SELECTION.

*Do your coding here

<b>in this way we are deferring the class definition for later</b>
