Hi Dan, if you want to use a RETURNING parameter when you call you method, you need to define the parameter as a RETURNING parameter in your class definition.


    METHODS get_data RETURNING VALUE(e_data) TYPE char20.

You had defined it as an EXPORTING parameter, which means that when you call the method you would have need to use this syntax instead.


   object_reference->get_data( IMPORTING e_data = var ).

Hi Rich,

I still want to use exporting param as :

METHODS get_data exporting e_data TYPE char20.

and called the method as u suggested it is throwing an error saying " statement object_reference->get_data( is not defined ".

Can you please suggest?

Thanks

Dany

H Dan, if you would like to use the EXPORTING parameter, then you must write you method call like this.


object_reference->get_data( importing e_data = var ).

If you are on an earlier release, then you must use the CALL METHOD as well.


CALL METHOD object_reference->get_data( importing e_data = var ).

Regars,
