I definately missed this, but I discovered a different behavior in the flat file pipeline assembler component.
In BizTalk 2004, you needed to define the flat file schema in the pipeline component, otherwise, on compile, you will get an error.
However, in BizTalk 2006, you don’t need to specify a flat file schema in the flat file assember component. BizTalk will determine which schema to use and create the flat file during run time (run-time schema discovery is done).
Anyway, I thought that this is an interesting, usable new behavior, as I have a lot of interfaces that I no longer need to create a seperate flat file pipeline for each file, I can reuse a common flat file pipeline.
