I have implemented File to RFC to File scenario. I had it working just fine but have been posed by the following error on the Sender file adapter
Error: com.sap.engine.interfaces.messaging.api.exception.MessagingException: XIServer:MSGGUID_EXISTING:
I have tried the following
1. Start/stop channel
2. Restart XI server - In the past we had this problem and restarting the XI server did the trick.. but not working this time around.
Thanks, any help is appreciated
