BizTalk Correlation in Orchestrations

Question

Hello All,
I have a scenario in which in am calling an SP and it gives me a response. Now lets call the messagetype of Request Msg as Arequest and messagetype of Response Msg as Aresponse. There is a node in Arequest called ID. I am in innitialising a correlation in
Orchestration for that ID while sending the data to SP. when I recieve the response from SP I check if it is a 1 or a 0 if it is a 0 I have a receive shape with a following correlation of ID and a different messagetype say Debatch. If I get a 1 from SP I call
a view which will return a response with N number of ID. now I have to debatch for each ID to a messagetype debatch and then publish to the messagebox so that it can be subscribed by the dehydrated orchestrations (the receive shape that I was using for dehydration
earlier!) I am able to do all this but after debatching the orchestration I am getting a routing failure error in BizTalk. When I check the subscriptions for the suspended orchestaration the subscriptions are 1. for the the ID and 2 for the messagetype as
the root node of the debatched message.
please help

The send would been the result of some receive? you need to initialize on that receive and follow it up on the subsequent receive. That is how a "convoy" is created. A "convoy" is what will help you create the "order" that you
want. A "convoy" can be sequential - same receive location or parallel - different receive locations and/or different message types. Refer

https://msdn.microsoft.com/en-us/library/aa561843.aspx for Sequential Convoys and
https://msdn.microsoft.com/en-us/library/aa546782.aspx for Parallel Convoys.
You correlate between a send (initialize) and receive (follow) when you want to correlate a request to a response over an ASYNC transport such as Queues.
