Reading data from a file

Former Member — Thu, 07 Feb 2008 21:08:13 GMT

Hi Experts,

I have an internal table itab as below.

Data : begin of itab occurs 0,

first_name(10) type c,

last_name(10) type c,

end of itab.

I am passing some values to this internal table and sending the data to a file in app server say 'p_file'.

Now can u people give me the code to read the data back from the file in the application server back to my internal table..

Its bit urgent. <REMOVED BY MODERATOR>

open dataset p_file for input in text mode.

read dataset p_file into itab.

if sy-subrc ne 0.

exit.

else.

append itab.

clear itab

endif.

enddo.

close dataset p_file.
