hi

to create seq file

use

open dataset <filename> for output in textmode encoding default.

here u can loop at itab and transfer the data to dataset

close dataset.

u can see the file in tcode AL11

(application server files)

ex :

data : it_mara like table of mara with header line,

v_rec(60),

TAB(3) value ' ',

coma type c value ','.

*****************************creating file on application server************************

select matnr

mtart

ernam

matkl

meins from mara

into corresponding fields of

table it_mara.

open dataset 'matdet.txt' in text mode encoding default for output.

if sy-subrc <> 0.

exit.

endif.

loop at it_mara.

concatenate it_mara-matnr it_mara-mtart it_mara-ernam into v_rec separated by coma.

transfer v_rec to 'matdet.txt'.

• transfer it_mara to 'matdet.txt'.

endloop.

if sy-subrc = 0.

message i000(bctrain) with 'File created on application server'.

endif.

close dataset 'matdet.txt'.

Hi Rakesh,

check out the below code and you shall get the solution that you are looking for,

• Check for the existence of the file.

CALL FUNCTION 'TMP_GUI_GET_FILE_EXIST'

EXPORTING

FNAME = P_IPERR "file name along with the path

IMPORTING

ISDIR = L_ISDIR "-------L_ISDIR is a variable of Char (1)

EXCEPTIONS

FILEINFO_ERROR = 1

OTHERS = 2.

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 L_ISDIR EQ C_TRUE.

MESSAGE I000 WITH TEXT-<xxx>.

STOP.

ENDIF.

ENDIF.

• to create that file

OPEN DATASET P_IPERR1 FOR OUTPUT IN TEXT MODE. "----P_IPERR1 is the filename in the application layer.

CHECK SY-SUBRC EQ 0.

CLEAR WA_ERR_REC.

LOOP AT I_ERR_REC INTO WA_ERR_REC. "--I_ERR_REC is an internal table having the data to be written to flat file.

IF WA_ERR_REC-DEL_FLAG = C_TRUE.

TRANSFER WA_ERR_REC TO P_IPERR1.

ENDIF.

CLEAR WA_ERR_REC.

ENDLOOP.

CLOSE DATASET P_IPERR1.

ENDIF.
