Error in Edi Seperator Sender channel

Hi ,

While testing my scenario (EDI to file) am getting the below error in Edi Separator Sender channel

"com.sap.aii.af.lib.mp.module.ModuleException: senderChannel : Catching exception calling messaging system. Will deliver negative 997 if requested"

other than X12ConverterModule whether i need to add any Module parameters in sender channel in PI 7.31.

.
