related_conversation_group uid not same as GET CONVERSATION GROUP

[skg]

Gurus -
I am finding that the conversion groupid in the target proc is not the same
with what i am entered data in the queue using begin dialog conversion.

can any one explain why?

select * from sys.conversation_endpoints shows the correct
conversion group which i sending in the queue

Input data into the queue
========================
begin transaction

BEGIN DIALOG CONVERSATION @dh
FROM SERVICE [SourceService]
TO SERVICE 'TargetService'
ON CONTRACT [XMLValidationContract]
with related_conversation_group = 'A079C5FF-28D7-457C-B669-8066BEE8F06D',
encryption = off;

SEND ON CONVERSATION @dh MESSAGE TYPE [XMLValidationTemplate]
(<Info>12345</Info>)

commit transaction

Target que proc
=============================

create proc TargetProc
as
declare @ConversationGroupID uniqueidentifier

WAITFOR (
GET CONVERSATION GROUP @ConversationGroupID FROM TargetQueue),
TIMEOUT 1000

if(@ConversationGroupID <>'A079C5FF-28D7-457C-B669-8066BEE8F06D')
begin

raiseerror('Error".....

end

Converation group ids are different on each side of a conversation. Take a
look at sys.conversation_endpoints to see this in action. Also, specifying
related_conversation_group on a initiator (source) does not mean the
conversation ids are going to be the same on the target.

You can specify the converation group id on the initiator (source), but not
on the target. If you need to serialize messages so that the receives are
serialized on the target side, use a single conversation. If you need to
serialize the receives of the responses from different targets on the
initiator side, use a conversation group.

Hope this helps,
