We receive doc1, we transform doc1 to doc2.  We then have a decide shape tha
t branches based on a value in doc2.  THEN, in the two branches of the decid
e shape, we want to change the value of a distinguished field in doc2.

The Expression shape disallows and says we have to be in a construct message
 shape.  If we use an assign message (inside a construct) shape, we still ge
t the compile error that says "unconstructed message".  We know that it has 
been constructed.  Doesn't
the message keep flowing on forward.  Can you not change any of its values o
nce it has been constructed???

Hi Neal,

I've had this too. I think it's due to the way the BizTalk constructmessag w
orks.
When the construct shape starts, it will create a new instance of doc2, and 
the
original message will not be present.

One option you could take is to perform the map, then in the same construct
shape, add a message assignment shape below the transform. In this shape,
use an if statement to make the doc2 modification.

Cheers,

Alan.

Create a Temp message of Type Doc2
In the First Transformation use a message assignment in which assign
Temp = doc2

In the second construct message do the reverse of above
i.e doc2 = Temp
doc2.Distinguishedfield = "something"

I hope this will solve your problem

Regards
Raja

Might want to be little careful with message assignment, as biztalk does
not do the deep copy.  Might want to look at the documentation at
http://msdn.microsoft.com/library/e...g_orch_vwlg.asp for
further help on the topic
