Hi Friends,

I am doing the JMS -> IDOC Scenario.

This is working fine when the QoS : EO

I am getting a strange error when I changed the Qos from EO to EOIO. The message is in the status holding in RWB.

When I checked in the Queue, I got the error "XI Error NO_BACK_SYSTEM_IN_HOPLIST.INTERNAL: Queue"

Legacy system to which acknowledgment message is to be sent is missing in hoplist (with wasread=false)

What is the possible reason for this error and How to rectify this..

Thanks in advance

Hi !

Check note SAP NOTE 1078317

Summary

There was a bug in the XI message's HopListHeader class that caused this header to be cloned incorrectly.

Hi Matias,

Thanks for your reply.

We are using WMQTool for QueueManager. When I tested the Interface by putting the message thru RWB, it is working fine. When I send the message thru the QueueManager, it is not coming from the WMQTool to the XI. The message is not hitting the Communication Channel. When I see the Adapter Status, it is showing Sender channel. Details: (No detail information set.) in the CC. What is the possible reason for not coming from the WMQtool to XI.

Where as the Interface is working fine when I pass the message from the RWB.

Could you plz help ...

Thanks
