Method return value type conversion

[Former Member]

Hi all,

I'm new to Web Dynpro for Abap development and just experimenting with the basics.

I have the follwing code in a view:

DATA lv_return TYPE i.
  lv_return =   wd_this->get_next_index( ).

The methode declaration, declared in the same view is like that:

Parameter = RETURN

Type = Returning

RefTo = checked

Opt = unchecked

Associated Type = i

method GET_NEXT_INDEX .
endmethod.

The code line

lv_return =   wd_this->get_next_index( ).

produces the error

The result type of the function method cannot be converted into the type of LV_RETURN. type of LV_RETURN

What have I missed here? Any hint is highly appreciated!

Regards and thanks,

Hi Martin,

Uncheck the "ref to". This is to be used only for references of class/interfaces. Since your parameter is only an integer, ref to is not required. Uncheck it and it should work.
