Error with Filename

Question

Hi,
I am trying to get an Excel File Name using the function module KD_GET_FILENAME_ON_F4 on a Module Pool program. I can see the name of the file but when I click on it it just does not move the filename to the screen field.
Using the DEBUGger, I found that in KD_GET_FILENAME_ON_F4 when he calls the FM WS_FILENAME_GET it returns sy-subrc as 4 (selection error).
Could you please help me with this problem?
Here is the code sample.
Best regards.
CONSTANTS:   C_XLS(25)  TYPE C  VALUE ',Arquivos do Excel,*.XLS'.
CONCATENATE RLGRAP-FILENAME C_XLS INTO V_TEMPARQ.
      CALL FUNCTION 'KD_GET_FILENAME_ON_F4'
           EXPORTING
                STATIC    = ' '
                MASK      = V_TEMPARQ
           CHANGING
                FILE_NAME = RLGRAP-FILENAME.

Hi,
Try to use
DATA: LV_CNT TYPE I,
LS_FILENAME TYPE FILE_TABLE,
LT_FILENAME TYPE FILETABLE.
CALL METHOD CL_GUI_FRONTEND_SERVICES=>DIRECTORY_LIST_FILES
EXPORTING
DIRECTORY = 'C:'
FILTER = '*.*'
FILES_ONLY = 'X'
CHANGING
FILE_TABLE = LT_FILENAME
COUNT = LV_CNT.
LOOP AT LT_FILENAME INTO LS_FILENAME.
WRITE: / LS_FILENAME.
ENDLOOP.
