FTP to handle long text

Hi Experts,

   I'm doing a program to read and write the .CSV data in the FTP server using the functional module FTP_R3_TO_SERVER  &  FTP_SERVER_TO_R3. By using this functional module am not able to handle long text ( No of columns is more than 250 character ), but i can able to does this operation which is having the character length max of 250 . Kindly suggest me to handle this long text for the .CSV file in FTP.
