A Business Connector flow service is sending several custom (Z) idocs to SAP where they are processed by a custom function. The following are used to do this : CreateTID, OutboundProcess and Confirm TID.
The first idoc is processed ok but the flow service errors at confirmTID on subsequent idocs with the message
“com.sap.mw.jco.JCO$Exception: connection closed without message (CM_NO_DATA_RECEIVED)”.
The actual occurrence on which it fails varies it may be the second or it may get as far as the fifth and then fails.
Thanks in advance for any help.
