CALL METHOD cl_gui_frontend_services=>file_get_version

CHANGING

version = version

EXCEPTIONS

ERROR_NO_GUI = 2

NOT_SUPPORTED_BY_GUI = 3

Hi,

I tried using this method but i also failed to get the version.

Data: ws_version TYPE STRING.

DATA: ws_filename TYPE STRING.

ws_filename = 'D:New Text Document.txt' .

CALL METHOD cl_gui_frontend_services=>file_get_version
  EXPORTING
    filename             =   ws_filename
  changing
    version              =    ws_version
  EXCEPTIONS
    CNTL_ERROR           = 1
    ERROR_NO_GUI         = 2
    NOT_SUPPORTED_BY_GUI = 3
    WRONG_PARAMETER      = 4
    others               = 5
        .
IF sy-subrc <> 0.
 MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
            WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.

write :/ ws_version.

As Venkat mentioned, in the sample code it is mentioned as not implemented but in the same we are able to use file_open_dialog and file_close_dialog too.

So not clear,if i get some inputs will let u know.
