read return parameter of function module

martin_svik2 — Wed, 24 Feb 2016 11:12:16 GMT

hi,

i am calling an function module and get back lc_element:

lc_element is defined this way:

lc_element TYPE REF TO if_swf_cnt_element,

so far so good. when i set debugger after the call of the FM i get something like this when i click on lc_element:

i have NO idea of how to get the values of e.g. M_NAME or the values in the deep structure M_ELEM_REF. i can't loop over the lc_element as this is not an table.

so how can i access the data coming back into lc_element ?

br Martin

Hi Martin,

as lc_element refers to an object, you can use its interface to get the required values.

Hello Martin,

In you example, lc_element is a object reference to interface IF_SWF_CNT_ELEMENT which is embedded in class CL_SWF_CNT_ELEMENT where you can actually find implementation of several public methods.

So, to get the 'name' attribute for example, you will have to call the appropriate method, which I guess is GET_NAME:

DATA: lv_name type swfdname.

Call method lc_element->get_name importing NAME = lv_name.

Manu.

If you check the interface IF_SWF_CNT_ELEMENT, you will find a number of 'getter'-methods..

There is a GET_NAME for instance (and when you check the parameters, you can find out what the method returns):

example

CALL METHOD lc_element->get_name

IMPORTING

name = l_element.

Hi Martin.

Try,

DATA: lv_element TYPE REF TO CL_SWF_CNT_ELEMENT,

lv_name TYPE SWFDNAME.

IF lv_element IS BOUND.

lv_element->GET_NAME( IMPORTING NAME = lv_name

NAME_STRING = lv_namestring

EDITELEM = lv_element ).

ENDIF.

Hope it helpful,

Regards,

Venkat.

Try a


lc_element->get_name(
  IMPORTING
    name        = lv_name
    name_string = lv_name_string
    editelem     = lv_editelem ).

Of course add some check/If/try...

Raymond

thanks to all -> i have resolved it by calling the methods

i thougt i can read that out directly -> as the debugger displays this values directly.

Did you notice the red icon, those attributes are "private", so you need a method to read them.

(Also Hubert's answer was the first good one, so you should mark it as correct)
