Hi sahana,
but i dont have key field for item and trailer node ,so it is failing.Can some one help me with this ?
did you try other way around like putting the key field for item and trailer in the sender txt file?
change the configuration according to that and try it.
when you have multiples nodes then key field is needed in the configuration.
do the configuration exactly mentioned in the link
