use GUI_UPLOAD to read the data.

GUI_DOWNLOAD to save the data back.

u can do the required operations on the data on the data present in a internal table after the first fm

Hello Eswar,

You can do this by the following way.

Declare a Itab whcih has same structure as that of file.

Use GUI_UPLOAD to upload the file to the itab.,

Change the content of the itab.

Use GUI_DOWNLOAD to download the file.

If useful reward.

use fm 'WS_UPLOAD' to upload your data into internal table and then use 'WS_DOWNLOAD' to download the file and use the same filename.

CALL FUNCTION 'WS_UPLOAD'

EXPORTING

CODEPAGE = ' '

FILENAME = 'C:\file.txt'

FILETYPE = 'ASC'

HEADLEN = ' '

LINE_EXIT = ' '

TRUNCLEN = ' '

USER_FORM = ' '

USER_PROG = ' '

DAT_D_FORMAT = ' '

IMPORTING

FILELENGTH =

TABLES

DATA_TAB = internal table

EXCEPTIONS

CONVERSION_ERROR = 1

FILE_OPEN_ERROR = 2

FILE_READ_ERROR = 3

INVALID_TYPE = 4

NO_BATCH = 5

UNKNOWN_ERROR = 6

INVALID_TABLE_WIDTH = 7

GUI_REFUSE_FILETRANSFER = 8

CUSTOMER_ERROR = 9

NO_AUTHORITY = 10

OTHERS = 11

.

IF SY-SUBRC <> 0.

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

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

ENDIF.

CALL FUNCTION 'WS_DOWNLOAD'

EXPORTING

• BIN_FILESIZE = ' '

Hi

It depends on where the file u have to upload is.

Anyway to upload/download the file you have only two method:

- From Presentation Server: FM GUI_UPLOAD and GUI_DOWNLOAD

- From Application Server: statament OPEN DATASET/CLOSE DATASET

In both case I believe u should upload the data file into an internal table, modify the records in this table and downlad the records of the table to the file.
