I am the Technical Writer who has been working on the "Creating Custom Reports Using Configuration Manager SQL Views" document. This document will be much like the SMS 2003 version, but this time I will be bundling a Visio document that shows all of the views and which columns can be used to join them to other views – a relationship map by view category, and an Excel spreadsheet that lists the views and columns with the standard CHM file. The documents are currently going through our edit process and will hopefully be available to you on our download site by late October. I'll definitely let everyone know as soon as it's available.
