How to replace a multipart message schema in a map without replacing the map

I have an orchestration map that maps two source messages into one destination message. When the schem开发者_如何学Pythona for one of the source messages changes, I was hoping to be able to click on the input message part and select "Replace Schema" to refresh the schema for just the message part affected. Instead I can only replace the entire multipart message schema with the single message part schema.

My only other option seems to be to generate a new map from the orchestration transform shape, but this means I have to recreate all the links in my map...

Does anyone know of a more efficient way to update this type of schema?

I've decided for now to do this by modifying the xml of the map file. If anyone out there has any better ideas, I'd still like to hear them. Thanks!

After creating maps in the orchestration project, i moved them to maps project by copy and paste and change the namespace. Now everything looks good. But I found interesting problem.

When i try to reference these maps in the orchestraion I am able to see two schema namepaces under the maps references dll. one has newly moved maps and another one has old ones.

Can any one explain why? Is that sth i am doing wrong. or Biztalk 06 (vs2005) is behaving funny....

Then i created a new map in the Maps project and copied the xslt from orchestrioan map and pasted there. If i go with this approach i am unable to see two namespaces in the orchestraiton shape while referencing.
