Use Of Unconstructed Message Biztalk 2013
Join them; it only takes a minute: Sign up use of unconstructed message 'msg_mymessage' up vote 1 down vote favorite I have a BizTalk orchestration with an expression. The expression has the following: construct msg_mymessage { msg_mymessage = msgInputXML; } msgInputXML and msg_mymessage use the same schema, same message type and both show up under the Messages in Orchestration message has not been initialized in construct statement view. After the expression I have a Construct Message and in the Construct message I have a Transform that uses msg_mymessage as a source and some other message as a destination. I'm getting the errors: use of unconstructed message 'msg_mymessage' 'msg_mymessage':message has not been initialized in construct statement I'm not sure why I get this error. What should I be looking for? biztalk share|improve this question asked Feb 4 '12 at 1:40 dtc 4,878136290 add a comment| 4 Answers 4 active oldest votes up vote 2 down vote accepted Make sure that you use an assignment shape (inside a construct message wrapper) when you create msg_mymessage. Then just copy the code in the expression shape (msg_mymessage = msgInputXML;) http://msdn.microsoft.com/en-us/library/ee253499(v=bts.10).aspx share|improve this answer answered Feb 4 '12 at 12:50 StuartLC 62.6k1081131 Thank you. This fixed the build errors. I'm not sure how I got the error because all I did was switch out the schema. Before the schema switch it would build fine then after the switch it would no longer build until
of confusion and frustration! You try to build your orchestration and the build fails with the highlighted error below, for example: In my case, I'm trying to assign a value to a message but the compiler won't let me: instead, a copy of the

original message needs to be made and then the value can be assigned to the

copy. This is a core feature of BizTalk and demonstrates a tenet of the framework: received messages are immutable (can't be changed). What biztalk use of unconstructed message scope this means is that a full message audit trail is maintained which is critical when your application is "in the field" and a BizTalk admin needs to trace message processing through BizTalk using perhaps the BizTalk Admin http://stackoverflow.com/questions/9137706/use-of-unconstructed-message-msg-mymessage Console. So, for example, in the case of the orchestration below, I have an assign message shape (indicated with a red square) where I am incorrectly attempting to assign a value to the original message rather than a copy of it: In order to fix this, I need to make a couple of changes to the assign message shape: Modify the "Messages Constructed" property from the original message to a different message of the same type https://jamescorbould.wordpress.com/2013/04/16/use-of-unconstructed-message-messagename-error/ Change the message assignment: instead of assigning a value directly to the original message, I instead "clone" the original message and assign to this copy of the original message So in the expression editor, this: Becomes this:
Finally, I change the last Send shape to ensure that the message copy is sent rather than the original message. (Incidentally, a big clue that a new message needs to be created as part of the assignment is that the message assignment shape comes with a construct message shape). In conclusion, this post demonstrates a core feature of BizTalk: message immutability. This is a foundational principle of BizTalk as a framework and as demonstrated, is enforced by the compiler.

Meta Register Log in Entries RSS Comments RSS WordPress.com CategorieEnglish, Uncategorized by ibrhmoguz There is common issue that is "use of unconstructed message" when developing BizTalk project. Visual studio gives that error while compiling BizTalk https://biztalkapps.wordpress.com/2013/12/27/use-of-unconstructed-message-in-biztalk-orchestration/ project because we are trying to use message which has not yet initialized. In fact BizTalk message is a XML document. The first way to construct message follows; 1.Creating http://microsoft.public.biztalk.orchestration.narkive.com/M2ma8d8P/help-use-of-unconstructed-message-message-has-not-been-initial a message with the help of a System.XML.XMLDocument variable. We have to first declare an orchestration variable of type XmlDocument.Then in a message assignment shape, need to do something like this: use of xmlDoc = new XmlDocument(); xmlDoc.LoadXML(“”) outputMsg= xmlDoc If we use outputMsg directly in the construct shape, it gives compilation error. We create instance of XmlDocument, the issue is resolved. 2.Create new message from an existing message using BizTalk map 3.Assign one message to other(i.e creating a copy of an existing message) Share this:Click to share on LinkedIn (Opens in use of unconstructed new window)Click to share on Twitter (Opens in new window)Share on Facebook (Opens in new window)Click to share on Google+ (Opens in new window)Like this:Like Loading...

and"message has not been initialized in construct statement"I'm creating an orchestration in BizTalk 2006. Biztalk is acting as a proxyweb service to the CRM web service (which has an awful API that we don't wantto expose to the outside world).Everything goes fine until I want to transform the response message from theCRM web service to my client response message (based on a schema I created).I can't use a Transform shape to create the message because for some reason,I can't get it to use the return web service message from the CRM as thesource for the transformation. So I am trying to use the Message Assignmentshape.I have tried the following code in the Expression Editor (all fields aredistinguished, OnyxOrgRegResponseMessage is from the CRM):PartnerOrgRegResponseMessage.Message =OnyxOrgRegResponseMessage.ExecuteResult;PartnerOrgRegResponseMessage.SuccessFailure = "Default";On build, I get the "use of unconstructed message". I can try this code (inthe Expression shape):construct PartnerOrgRegResponseMessage{PartnerOrgRegResponseMessage.Message =OnyxOrgRegResponseMessage.ExecuteResult;PartnerOrgRegResponseMessage.SuccessFailure = "Not Set";}or this code (in the Message Assignment or Expression shapes):PartnerOrgRegResponseMessage = new System.Xml.XmlDocument();PartnerOrgRegResponseMessage.Message =OnyxOrgRegResponseMessage.ExecuteResult;PartnerOrgRegResponseMessage.SuccessFailure = "Not Set";which both build fine, but give me this error on execution:Inner exception: A failure occurred while evaluating the distinguished fieldMessage against the message part data. The message part data does not containat least one of the nodes specified by the XPath expression (listed below)that corresponds to the distinguished field. The cause for this error may bethat the message part da
