This seems to be a big complaint, there are many companies that would like to have access to the envelope information in the map. There are a few VERY KLUDGY ways of getting data from the message into the map. All of them are VERY BRITTLE. The EDI logger now will create an additional message part called 'envelope' and send it to the message box.
If you are familiar with the multi part message that the BTAHL7 accelerator creates, this will be a breeze. For those of you not in the provider world, I will walk through the instructions on how to create a process to access the envelope information (you will see that there is a LOT more than just the envelope information).
To start off with, there are now two message parts to the message that shows up in the message box. The body part is the transaction itself (so you can still use the message in a send port map if necessary).
Here is a screen shot of the multi part message:
The schema that is deployed to the GAC that you can reference (C:\WINDOWS\assembly\GAC_MSIL\EDIArchiveProperties\188.8.131.52__e7dd178931a8d66e\EDIArchiveProperties.dll) in your project that will host your orchestration has this structure (click to enlarge):
I normally create at least two different projects for each solution. One that represents the schemas, and the other that represents the mapping/orchestrations. For simplicities sake, I have called the schema project Schemas, and the location that I am going to put my maps and orchestrations will be called Logic. Here is a snapshot of the Solution Explorer:
I added the reference to the EDIArchiveProperties by adding a reference and pasting the dll mentioned above:
Let's create an orchestration, here you will want to create a multi-part message, making sure you define the body segment first and then the envelope segment second (click to enlarge):
Next you will create the necessary port and message from this multi-part message. I will jump to the creation of the map. You have a message defined from this multi-part type and you are mapping it to an output. You open up the map configuration dialog window and you fill in two lines, one that represents the envelope and the other that represents the EDI transaction on the input and the output message on the destination window.
And when pressing <OK>, this is the map that is created (click to enlarge), notice that the transaction is at the bottom of the source:
This allows you to access both the envelope and context data for that transaction, giving you the ability to map everything that would need to without going through a unnecessary hoops to get data injected into the message.
