read dataset <datasetname> into s_string.

if sy-subrc ne 0.

exit.

endif.

Use WHILE instead of DO in your case.

Hi Megan,

Small corection to the code.

read dataset <filename> for input in text mode encoding default.
do.
read dataset <filename> into itab-data.
if sy-subrc = 0.
append itab.
clear itab.
else.
exit.
endif.
enddo.

close dataset <filename>.

You have first open the file in text mode

OPEN DATASET myfile IN TEXT MODE ENCODING DEFAULT.

After that you introduce the loop to read the file record by record and if read fails you exit.

DO.
  READ DATASET myfile INTO myrecordstructure.
  IF SY-SUBRC <> 0.
*-- End of file reached
    EXIT.
  ENDIF.
......
..... rest of the processing with the current record
ENDDO.

Hi Megan,

Hope this code helps you.

Start-of-selection.

open dataset fname for input in text mode.

if sy-subrc <> 0.

message s999(z1) with 'File not found or cannot be opened'.

stop.

endif.

do.

read dataset fname into i_upload.

if sy-subrc <> 0.

exit.

endif.

append i_upload.

clear i_upload.

enddo.

close dataset fname.

Hi,

Please try this.

*   Retrieve Data file from Application server(Upload from Unix)

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.
