RE: Transaction import by Application server error
Is your Application Server a real PC or some kind of a virtual environment?
If you deploy Application Server in a terminal server environment, some transaction imports may halt if the session is on standby mode. The Application Server might still be able to perform other processes, though.
This is pretty technical, but the Transaction Import needs an active Window Station to work properly. The effect is similar to having the minimize check on. This behavior is different depending on the particular screen. The Purchase Order screen is known to work only non-minimized.
If this is the case, there are some workarounds to make it work.
