STRINGS are variable in length. You can use STRLEN ( X ). TO FIND THE CURRENT LENGTH OF ONE.

Hi,

you can use the key word STRLEN to find the length.

data : text type string.
data: len type i.
len =   STRLEN ( text ).

and the fm is <b>F4_fielname</b>.

Hi Sonal,

You can use the method file_open_dialog of the class CL_GUI_FRONTEND_SERVICES to get the filepath to be used in BDC.

For eg:

at selection-screen on value-request for path.

CALL METHOD cl_gui_frontend_services=>file_open_dialog

EXPORTING

WINDOW_TITLE = 'Open File'

DEFAULT_EXTENSION = '.'

• DEFAULT_FILENAME =

• FILE_FILTER =

INITIAL_DIRECTORY = 'D:\SP'

• MULTISELECTION =

• WITH_ENCODING =

CHANGING

file_table = file_tab[]

rc = ret_code

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

.

Here <b>file_tab</b> will contain the path you have selected and <b>ret_code</b> will contain value of either you have clicked OK button or CANCEL button.

Hi Sonal,

i do it on this way:

...

PARAMETERS: P_FILE LIKE RLGRAP-FILENAME

DEFAULT 'D:\SAP\*.TXT'.

...

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_FILE.

*

DATA: PATH LIKE RLGRAP-FILENAME VALUE 'D:\SAP\'.

*

CALL FUNCTION 'WS_FILENAME_GET'

EXPORTING

DEF_FILENAME = SPACE

DEF_PATH = PATH

MASK = ',.txt ,.txt.'

MODE = 'O'

TITLE = 'PC-File-Selection'

IMPORTING

FILENAME = P_FILE

EXCEPTIONS

INV_WINSYS = 1

NO_BATCH = 2

SELECTION_CANCEL = 3

SELECTION_ERROR = 4

OTHERS = 5.

Hi Sonal,

Here is the sample code.

REPORT ZSHAIL_FILEPROG .

data: it_tab type filetable with header line,

gd_subrc type i.

tables: rlgrap.

selection-screen: begin of screen 200.

parameters file_nam type rlgrap-filename .

selection-screen: end of screen 200.

data: user_act type i.

start-of-selection.

call selection-screen 200.

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 =

DEFAULT_FILENAME = ''

FILE_FILTER = '*.txt'

INITIAL_DIRECTORY = 'D:\SP'

• MULTISELECTION = 'X'

• 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'.

read table it_tab index 1 .

file_nam = it_tab-filename.

endif.

Dieter,

I think WS_FILENAME_GET is an obsolete Function Module.

Use <b>F4_FILENAME</b>

Hi Sonal,

What is your requirement exactly??

If you want to upload data from a flat file, just go through the program in my previous post. It will work..

The path will be stored in the <b>file_nam</b>.

Now you have to use GUI_UPLOAD to upload the data .In that Function Module, jsut give file_nam as the parameter for the path.

Hi Sylendra,

i think you are right.

CALL METHOD cl_gui_frontend_services=>file_open_dialog

...

is the better one and i will it use.

Thanks for the Info.
