Hi,

Use dataset for that

refer this code

&----

*& Form open_file

&----

form open_file.

if p_aserv eq 'X'.

open dataset p_path for output in text mode encoding default.

if sy-subrc ne 0.

WRITE 😕 'Download Failed'.

message e000(8i) with 'Error in File opening for download'.

endif.

endform. " open_file

Loop on internal table

if p_aserv eq 'X'.

transfer wa_bsik_s to p_path.

elseif p_aserv1 eq 'X'.

move wa_bsik_s to i_out.

concatenate

Regards,

Prashant

i am sending you a code

in which i had wrote the logic like this

data from file to internal table

internal table to application server

by seeing this you can understand very easyly

reward if usefull

if you want to put data into application server you ned to use this code

OPEN DATASET p_file FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.

*--- Display error messages if any.

IF sy-subrc NE 0.

MESSAGE e001(zsd_mes).

EXIT.

ELSE.

*---Data is downloaded to the application server file path

LOOP AT it_tab2 INTO wa_tab2.

TRANSFER wa_tab2 TO p_file.

ENDLOOP.

ENDIF.

*--Close the Application server file (Mandatory).

CLOSE DATASET p_file.

there is no FM for this
