IDXQUEUE entry

I needed to serialize idocs while they were sent from r3 to xi. It worked fine with me when i reffered to the blog.

Setting up inbound qRFC queues for serializing IDocs using the IDoc Adapter and it worked fine.However i need to send the idoc with same message type with different values in mescod and mesfct to be routed to different queues. eg if message type = ZIDOC, mescod=aa and mesfct=bb then it must hit the queue zidocab, if mescod=ZIDOC , mescod=cc,mesfct=dd, it must hit the queue zidoccd. How should i make the table entry in idxqueue.

Please help.
