Open and Close Dataset problem

Question

Hi All,
I am facing a weird problem in transferring data to application server.
I have used Open dataset to write my file in text format to the application server.
Now everything works fine when small amount of data is there.When the number of records increases and when it takes lot of time , the format of the text file is completely distorted.
I have used tab as the delimiter. Please suggest me some solution for this.
Is this due to the time taken?
Regards.

Hi
in the above program , when i had created 1st i had same problem
then i had worte the logic likethis
parameter: file_nm type localfile.
types : begin of it_tab1,
        f1(20),
        f2(40),
        f3(20),
       end of it_tab1.
data : it_tab type table of ALSMEX_TABLINE with header line,
       file type rlgrap-filename.
data : it_tab2 type it_tab1 occurs 1,
       wa_tab2 type it_tab1,
       w_message(100)  TYPE c.
at selection-screen on value-request for file_nm.

data : p_file TYPE  rlgrap-filename value 'TEST3.txt'.
OPEN DATASET p_file FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.

i had wrote that logic for that
reward if usefull
