hi,

use opendatset statemnt in read mode ( i.e input)

open dataset <name> for INPUT in BINARY MODE / TEXT MODE.

Example

DATA: file TYPE string VALUE 'test.txt'.

OPEN DATASET file FOR INPUT IN TEXT MODE

ENCODING DEFAULT .

WHILE sy-subrc = 0.

READ DATASET file INTO result.

WRITE / result.

ENDWHILE.

CLOSE DATASET file.

hii,

for reading a file from application server you can use this code



data:
    w_file(50) TYPE c VALUE 'file1.txt'.

OPEN DATASET w_file FOR INPUT IN TEXT MODE ENCODING DEFAULT.
  DO.

   READ DATASET w_file INTO fs_bkpf.
      IF sy-subrc EQ 0.
      WRITE: fs_bkpf.
        APPEND fs_bkpf TO t_bkpf.
      ELSE.
        EXIT.
      ENDIF.                           "  IF sy-subrc EQ 0

  ENDDO.
  CLOSE DATASET w_file.

Hi,

OPEN DATASET FNAME IN TEXT MODE FOR INPUT ENCODING DEFAULT.

DO.

READ DATASET FNAME INTO IT_TAB.

IF SY-SUBRC 0.

EXIT.

ENDIF.

APPEND IT_TAB.

ENDDO.

CLOSE DATASET FNAME.

Hi,

wf_filename = Path on application server.

IF wa_file-file_type = 'BIN'.

OPEN DATASET wf_filename FOR INPUT IN BINARY MODE.

ELSE.

OPEN DATASET wf_filename FOR INPUT IN TEXT MODE.

ENDIF.

IF sy-subrc EQ 0.

READ DATASET wf_filename INTO wf_row.

Tab delimited File

SPLIT wf_row AT co_tab INTO TABLE tb_data.

or

; delimited File

SPLIT wf_row AT ';' INTO TABLE tb_data.

endif.

Now tb_data contains the data from the application server.

Hi,

to upload data from Application server we have to use open dataset To open a file on the application server, use the OPEN statement as follows:OPEN DATASET <dsn> [your file name].

To read data from a file on the application server, use the READ DATASET statement:

and we have to use close dataset to close rhe file...

close dataset (your file name).

READ DATASET <dsn> INTO <f> [LENGTH <len>].

DATA FNAME(60) VALUE 'myfile'.

DATA: TEXT1(12) VALUE 'abcdefghijkl',

TEXT2(5),

LENG TYPE I.

OPEN DATASET FNAME FOR OUTPUT IN BINARY MODE.

TRANSFER TEXT1 TO FNAME.

CLOSE DATASET FNAME.

OPEN DATASET FNAME FOR INPUT IN BINARY MODE.

DO.

READ DATASET FNAME INTO TEXT2 LENGTH LENG.

WRITE: / SY-SUBRC, TEXT2, LENG.

IF SY-SUBRC <> 0.

EXIT.

ENDIF.

ENDDO.

CLOSE DATASET FNAME.

dhaya.

hey krupali,

well for uploading the data from the presentation server,

tou are to use the "open dataset "statement.

as

Hi,

OPEN DATASET <name of the file> IN TEXT MODE FOR INPUT(since you are fetching values from the server) ENCODING DEFAULT.

DO.

READ DATASET <name of the file> INTO <internal table>

IF SY-SUBRC 0.

EXIT.

ENDIF.

APPEND <internal table.>

ENDDO.

CLOSE DATASET <name of the file>.

reward if helpful

take care

Hi,

Please refer the code below:


DATA: i_file like rlgrap-filename value '/usr/sap/tmp/file.txt'.

    OPEN DATASET i_file FOR INPUT IN TEXT MODE.
    IF sy-subrc NE 0.
      MESSAGE e999(za) WITH 'Error opening file' i_file.
    ENDIF.
    DO.
*     Reads each line of file individually
      READ DATASET i_file INTO wa_datatab.
*     Perform processing here
*     .....
    ENDDO.

Thanks,

Sriram Ponna.
