Hi divya,

use the FM tmp_gui_file_open_dialog.

it opens a dialog for the user to search for a file..

a sample..

DATA itab LIKE TABLE OF FILE_TABLE WITH HEADER LINE.
data : filename type string.
*filetable type standard table of file_table with header line,

SELECTION-SCREEN BEGIN OF BLOCK b1.
PARAMETERS : DATASET(128).
SELECTION-SCREEN END OF BLOCK b1.



AT SELECTION-SCREEN ON VALUE-REQUEST FOR DATASET.

CALL FUNCTION 'TMP_GUI_FILE_OPEN_DIALOG'

* EXPORTING

*   WINDOW_TITLE            =

*   DEFAULT_EXTENSION       =

*   DEFAULT_FILENAME        =

*   FILE_FILTER             =

*   INIT_DIRECTORY          =

*   MULTISELECTION          =

* IMPORTING

*   RC                      =

  TABLES

    FILE_TABLE              = itab

* EXCEPTIONS

*   CNTL_ERROR              = 1

*   OTHERS                  = 2

          .

IF SY-SUBRC <> 0.

 MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.



READ TABLE ITAB index 1.

  DATASET = itab-FILENAME.

Hi Divya,

You can use the class CL_GUI_FRONTENDSERVICES.

Here is a program to display a search screen for flat file..

REPORT ZJAYRA_FILEPROG .

data: it_tab type filetable with header line,

gd_subrc type i.

tables: rlgrap.

parameters file_nam type rlgrap-filename .

data: user_act type i.

at selection-screen on value-request for file_nam.

CALL METHOD cl_gui_frontend_services=>file_open_dialog

EXPORTING

WINDOW_TITLE = 'select a file'

DEFAULT_EXTENSION = '*.txt

DEFAULT_FILENAME = ''

FILE_FILTER = '*.txt'

INITIAL_DIRECTORY = ''

MULTISELECTION = abap_false

WITH_ENCODING =

CHANGING

file_table = it_tab[]

rc = gd_subrc

USER_ACTION = user_act

FILE_ENCODING =

EXCEPTIONS

FILE_OPEN_DIALOG_FAILED = 1

CNTL_ERROR = 2

ERROR_NO_GUI = 3

NOT_SUPPORTED_BY_GUI = 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.

if user_act = '0'.

loop at it_tab.

file_nam = it_tab-filename.

endloop.

endif.

Hope your query is solved.

Regards,

Sylendra.

Hi Divya,

the FM ws_filename_get is given

"OBSOLETE: Call File Selector" in its description..

thats why i suggested you the ABove mentioned FM..

hi Divya,

WS_FILENAME_GET function module is obsolete, and results in errors on Unicode systems.

Suggest to use FILE_OPEN_DIALOG und FILE_SAVE_DIALOG Unicode-enabled methods of the cl_gui_frontend_services class.

Note:

New applications should restart on these methods instead of the function module. The function module is extended by a Support Package so that it diverts calls to the methods without the application having to be changed.
