Problem to call a easy function in a transformation routine

Question

Hi,
I wanted to convert a string ("12") to an integer (12) in my transformation routine.
Here the code:
DATA: vaca_number TYPE i.
    CALL FUNCTION u2019conversion_exit_alpha_outputu2019
      EXPORTING
        input  = source_fields-vaca
      IMPORTING
        output = vaca_number.
    IF source_fields-smocker CS 'Y'.
      result = vaca_number * 120.
    ELSEIF source_fields-smocker CS 'N'.
      result = vaca_number * 240.
    ELSE.
      monitor_rec-msgid = 'ZMESSAGE'.
      monitor_rec-msgty = 'E'.
      monitor_rec-msgno = '001'.
      monitor_rec-msgv1 = 'ERROR SMOCKER UNKNOWN FOR PPS'.
      monitor_rec-msgv2 = source_fields-smocker.
      APPEND monitor_rec TO monitor.
      RAISE EXCEPTION TYPE cx_rsrout_abort.
    ENDIF.
When i check, i have the following error:
E:"RS_C_ICON_VERSION-" expected, not "#CONVERSION_"
Have you an idea ?
Thanks for your help.

That's one problem.  But if you look at the interface for the FM, it requires a character value.  The following, using an integer, will dump.  Try it and see.  The only way to make it work is to define i_2 as a character, not integer.
PROGRAM zz_temp.
DATA:
  c_1  TYPE c VALUE '1',
  i_2  TYPE i.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
  EXPORTING
    input  = c_1
  IMPORTING
    output = i_2.
