We are using EDI conversion from classic which is working fine but the same code running from RTC gives 'An I/O exception occurred during the operation'.
What to find the cause of solution of it?
I think if it was an automation issue it would probably give a different error message.
You need to remember that FILE operations in classic NAV run on the machine the user is running the NAV client on (using user permissions) whereas in RTC FILE operations are being run on the middle tier (using permissions for the account running the NST).
