811 mapping question


I’m not new to EDI or webMethods, but I am new to the 811 transaction. I’m wondering if anyone knows of code samples for the 811? In particular, I’m trying to understand how to break out the HL levels. I’m involved in a brand new implementation of webMethods 8.2 and in the past have used 6.1/6.5.

Any help would be greatly appreciated.
