I am using message broker version 5 csd5. I have vendor software dropping a message on my request queue with a jms header containing the vendor's replyto queue. I need to send the message through the SAP adapter and have it return to my reply input queue, THEN drop it back on the vendor queue. However, when the message comes out of the adapter, the adapter puts it directly on the specified vendor queue, bypassing my reply flow transformation and causing the vendor program to crash.
From the manuals, it looked like I could just change the jms replyto queue data to point to my reply flow input queue, but the message crashed the adapter (WBI adapter for mySAP.com v5.5). I was told this was because I corrupted the "envelope" by changing the value and the adapter couldn't handle it. I finally deleted the entire jms header. While this worked, the vendor does not like having the queue name removed. In truth, it does not seem like a very elegant solution. 
Could someone please suggest a better way? I am told the vendor can not change the queue name, so it falls on me to do it within the message broker.
Thanks for any help you can provide. |

I guess it depends on how you did it, but broker should be able to transparently update the JMS portion of an MQRFH2 header. If you treated it as a BLOB and just did text replaces, I could see that breaking things...
Your MQ Administrator should be able to configure things such that the replyto queue that the adapter is writing to gets resolved to a different queue that is your input queue. But then when you try to write to the output queue, it actually goes to the vendor replyto queue.

Thanks for your response, Jeff!
I used "SET OutputRoot.MQRFH2.jms.Rto = 'xxx';" to set the queue. This may have been the wrong way to do it (my jms knowledge is non-existent and I am an MB novice), but it looked like it worked when I checked the results in RFHUTIL. Should I have used something else?
I had not considered changing the adapter queue. That sounds like a good suggestion, but we use that queue for ALL messages coming out of the adapter. It is set up as an alias queue referencing a router flow input queue. The message did not even hit our router flow. It went directly to the vendor queue. |

| Set ReplyToQ of MQMD field & see what happens. Worth giving a try eventhough your MQRFH2 setting should have taken precedence. |

| Thanks, Sieijish. I did try that. It was ignored. |
