Does anyone know what is the main cause?
The shortdump description is:

I do not know what is missing here.

Hi,
Though there are a lot of importing parameters, you should give only one structure for outtable, and read as index 1 and index 2.
FORM GET_SPRAS TABLES intable   STRUCTURE itcsy
                                          outtable  STRUCTURE itcsy.
  DATA: lv_kunnr LIKE kna1-kunnr.
  CLEAR: GV_SPRAS.
  lv_kunnr = intable-value.
  CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
    EXPORTING
      input  = lv_kunnr
    IMPORTING
      output = lv_kunnr.
  SELECT SINGLE LAND1 SPRAS INTO (gv_land1, gv_spras) FROM KNA1
    WHERE KUNNR = lv_kunnr.
  IF sy-subrc = 0.
    READ TABLE outtable INDEX 1.
    outtable-value = gv_spras.
    MODIFY outtable INDEX 1.
    READ TABLE outtable INDEX 2.
    outtable-value = gv_land1.
    MODIFY outtable INDEX 2.
  ENDIF.
  IF gv_land1 EQ 'DE'.
    CLEAR: GV_LAND1,
           GV_SPRAS.
  ENDIF.
ENDFORM.
