data: begin of it_filedir occurs 10.

include structure salfldir.

START-OF-SELECTION.

Get Current Directory Listing for OUT Dir

call function 'RZL_READ_DIR_LOCAL'

exporting

name = p_fdir

List of files are contained within table it_filedir

Hi Punit

you can assign F4 help to any parameter on selection-screen using

PROCESS ON HELP REQUEST FOR <field> event for that particular parameter

Thanks

Hi Punit,

This question has been asked a number of times. Just check this code.

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.

This will work.

Regards,

SP.

Hi Punit,

you can use MATCHCODE OBJECT in select options.

eg.

SELECT-OPTIONS: S_MATNR FOR MARC-MATNR MATCHCODE OBJECT S_MAT1,

or,

You can use this function module

F4IF_INT_TABLE_VALUE_REQUEST

In this function module you pass internal table values.

Suresh

Hi Ashok,

I am writing a BDC. I am searching for a FM which will open a window so that user may select a file and return the path of the selected file.

The path returned by the FM will be provided to FM 'GUI_UPLOAD'.

Is this is possible with this FM 'F4IF_FIELD_VALUE_REQUEST'

Use this Function Module and code to open application server file

Open Dialog Box for Application Server files

CALL FUNCTION '/SAPDMC/LSM_F4_SERVER_FILE'

IMPORTING

serverfile = app_fp

EXCEPTIONS

canceled_by_user = 1

OTHERS = 2.

IF sy-subrc <> 0.

Check error

ENDIF.

Hi Punit,

You can try the method file_open_dialog

of the class cl_gui_frontend_services.

This will satisfy your requirement.

The path you selected will be stored in the parameter.

This can then be sent to other Function Modules.

This will work.

SP.

You can also try F4_FILENAME.

Punit,

GUI_UPLOAD, I don't think it will work for app servers. Please go through the thread I have referred in my earlier posts.

More over, CL_GUI_FRONTEND_SERVICES will NOT work for app servers as well as in the background.

Please choose the right funciton.

Ravi
