Multiple Messages in Same JMS queue

Question

Hello,
I have interfaces in which different xml messages from the same sender system will be placed in the same MQ queue, is there a way that XI JMS sender channel can differentiate the xml messages based on the payload?
I can create a single communication channel, but the outbound message interface I cannot create a common structure because the xml messages are huge and there will be future interfaces following the same architecture.
1. How can I route in interface determination based on the context in the inbound msg interface?
2. What can I provide as Message interface for the outbound?
3. MessageSelector attribute in Adapter specific properties - any ideas on this? - I can select this in the condition context in interface determination - can I give any values here to differentiate msges?
4. Value mapping - is it possible to define the sender message interface through this?
Any idea is appreciated..THank you..

Hi Thanujja,
We have recently completed a project that had this requirement too. We made use of the MessageSelector to solve this problem. You'll need to make use of some advanced (advanced tab)settings in the comm channel. Basically you want to add Additional JMS Message Properties. You can add up to 10 additonal JMS Properties.
Let's say you've added a property called MESTYP. You then need to get the sender to populate the MESTYP property with a text value for each IDoc involved e.g. DELVRY. You would then set your JMS Message Selector field as follows: MESTYP='DELVRY'.
You'll have a comm channel for each IDoc. These comm channels will then connect to the JMS Queue & only pick up messages that meet the criteria at set in the Message Selector.
There was one other problem that encountered with Message Selector, we were on XI version 7.0, the Message Selector was working intermittently & then we applied SAP Note 1256636 & upgraded to 7.01. Everything is working fine after that.
