I am not new to BizTalk however this situation is somewhat new. I have below situation in an BizTalk Orchestration,
I get path of flat file from some other source.
I want to load this file in orchestration and disassemble it by executing pipeline.
I searched a lot but almost every one talks about feeding a XML document in pipeline inside orchestration.
I got below links too but I couldn't get the working solution so far,
Calling FlatFile pipeline inside orchestration
4 Different ways to process an XLANGMessage
When I implemented solution given at above links, I get error "No Disassemble stage components can recognize the data."
I also don't want to create dynamic receive locations because of performance constrains.
Below is my code so far,
Load file content in a stream
Create a CustomBTXMessage instance as suggested in link two.
Load stream as below
customBTXMessage = new CustomBTXMessage("MyMessageName",
Service.RootService.XlangStore.OwningContext);
customBTXMessage.AddPart(string.Empty, "Body");
customBTXMessage[0].LoadFrom(ms);
return customBTXMessage.GetMessageWrapperForUserCode();
I think this situation is not something new in BizTalk world. Any one who has done this must be able to help me quickly.
Here's what I would do...or at least try first.
Create a Receive Port and Receive Location for each Flat File type you get.
Get the list of files.
In the Orchestration, Move the file to the appropriate Receive Location.
Flat File Disassembler the file in Port Pipeline like normal.
Receive the File into the Orchestration with an Ordered Delivery Port bound to the Receive Port from Step 1.
Loop on Receiving the files, checking for BTS.LastInterchagneMessage.
When True, Exit that Loop and go back to step 3.

I am building an integration that should fetch a zip-file from SFTP and save it as XML on disk. I have got everything working except the unzip-part...
The integration looks like this.
Receive location polls the SFTP, and in the receive port "Inbound maps" I have provided a mapping schema (converting the txt-file in the zip file to XML).
Receive location: polls the SFTP, custom receive pipeline.
Custom pipeline: In Disassemble first the unzip-component from BizTalk Utility pack ( BizTalk Server 2020 – 20 days, 20 posts: Unzip File Pipeline Component for BizTalk Server 2020) and then the flat file disassembler. The document-schema here matches the source-schema in the mapping.
Send port: Save file on disk.
The problem is that when I run the integration, the file is picked up from the SFTP and the file is indeed unzipped but the send port saves the content from the original file to the send-location. It is as if the mapping is never executed.
But if I remove the unzip-component in the custom pipeline and manually unzip the file and upload the content (.txt-file) to the SFTP everything works fine.
As per Sandro Pereira's instruction no configuration is needed, so I don't really understand why it is not working.
Receive Pipelines - Disassemble stage (Microsoft.com)
If this stage contains more than one component, only the first component that recognizes the message format is run. If none of the components within the stage recognize the message format, the message processing fails.
So you can't have both in the disassemble stage of the pipeline and have them both execute. Move the Unzip to the Decode stage of the pipeline.
I have built a flatfile schema with the flatfile schema wizard.
The schema is valid and I could successfully validate my test instance against the schema.(So the XML file was created correctly).
But when I put my test flat file into a receive location that uses a flatfile disassembler pipeline, nothing happens after the receive location has picked up the message (the logical receive port is bounded to an orchestration)
In the BizTalk Admin Console I only see in the tracked message events from the pipeline that the message has been received. But not sent.
Maybe some of you already had a similar issue and could help me here.
Tracked message events in the pipeline
So. The issue was a wrong declared header schema. I have rebuild it and after that it was working fine.
I have recognized the issue by removing the header schema from the pipeline properties and trigger a new process. At this time the message was created correctly (but with the header line due to a missing header schema that would prevent that line).
Thanks to all who helped here!
I'm looking to loop data received from SQL Server data received from wcf-sql adapter.
I use for loop and and the following
itostring=i.ToString();
MessageOne=xpath(MessagePolling,"/*[local-name()='MainData' and namespace-uri()='http..["+itostring+"]");
When the XPath in for the first receive message path[i]
Is this the correct way?
There are two ways^ to loop on multiple records contained within an Xml message received by BizTalk:
Envelope Schemas
When you define the schema that represents the message, mark it as an Envelope Schema. This tells the Receive Pipeline Disassembler to create (and publish) one message to the BizTalk Message Box for each record in the incoming message (in your case from the WCF-SQL Adapter). This will cause a single Orchestration instance to be started for each record in your incoming message.
Richard Seroter has a great blog post on doing this from the WCF-SQL Adapter - http://seroter.wordpress.com/2010/04/08/debatching-inbound-messages-from-biztalk-wcf-sql-adapter/
Be aware that with this approach, you don't want to be de-batching tens of thousands of records from the incoming message as BizTalk will grind to a halt :-)
XPath Inside an Orchestration
If you do not use an Envelope Schema, you will start a single Orchestration instance for the incoming message (containing multiple records). Within an Expression Shape in your Orchestration, you can use XPath (and some other magic) to loop around each record an extract each to an Orchestration variable (which you can then map on etc.)
Take a look at the following links that will help you with extracting via XPath:

^There is also a third way to achieve this as of BizTalk Server 2009 (I think - it seems like so long ago) whereby you can execute a Receive Pipeline within an Orchestration, so you could perform your Envelope de-batching in an Orch, instead of a Receive Location's Receive Pipeline.
I'm relatively new to Biztalk and I'm having a bit of hassle with this:
I have built a simple orchestration, hooked it up correctly to a receive port, I'm using the correct schema and map and the orchestration seems to be subscribing ok.
However, when the file I want to process gets picked up at the port I'm getting the 'could not be routed because no subscribers were found' error.
I ran a HAT query and can see the orch has an active subsription to the correct thing, is there anything else I can check on this?
Is your port hooked directly to the orchestration or is the orchestration picking the message up from the message box? Has the orchestration receive been set to Activate?
What does your subscription filter look like for the orchestration?
As a futher test:
a) create a sendport (FILE)
b) add a filter to it; BTS.ReceivePortName =
c) grab the resulting file - it should be the XML thats produced by your Custom PL
d) Use this file with a receive location using an XML Receive PL and see how your orchestration reacts to
This will at least rule out a Pipeline issue...
HTH
Check your pipeline is XMLReceive. This will promote the MessageType property and hopefully your orchestration will subscribe successfully.
Find the failed message in HAT and look at the body of the message. Copy it out and then run validate it against the schema of the message you are expecting. If it doesn't validate then you have set your flat file disassembler up incorrectly.
I want to pull something from the server (no delete), parse the file in the pipeline component, process the file, if everything goes successfully, I want the adapter delete the file.
i am thinking to enlist the parsing into the pipeline context, this way, I am picturing if the file cannot be parsed, the file will not get to the message box, therefore it will be deemed as a failed transaction, question, will the adapter participate in this transaction? in other words, my goal is to instruct the adapter to delete the file from the server ONLY when the pipeline processed successfully (transaction is commited), the file is left untouched on the server if the pipeline failed (transaction is rolled back, no message is commited to msg box)
Is this achievable? thanks in advance
I think a little experiment is in order. BizTalk, as part of it's nature, will not delete anything until it has been peristed to the message box. That being said, persitence might happen before PipeLine execution. So, the receive adapter receives the file, perists it to the message box and deletes the file. The message might subsequently fail in the pipeline. If this is the case, then the message is a bad format and it will have to be subsequently resubmitted by the sender. If you want to keep this message, you'll have to pick it up with Failed Message Routing. You can then write it to a directory and implement a resubmit pattern. Or, you can pick up the file via Failed Message Routing and put it back on the FTP server (this is sort of a compensation step).
On the otherhand, if the pipeline fails and the message isn't deleted fromt he server... you're fine.
