Tracking In BizTalk Server 2006
The Health and Activity Tracking tool (HAT) has lost quite some functionality in BizTalk Server 2006 compared to the 2004 version. Actually that's not a bad thing since all the lost functionality has been ported to the BizTalk Server Administration tool. Some time ago I was looking how to enable tracking for a specific message property in BTS 2006, it's not happening in HAT anymore, but in the Server Administration tool!

Q: How do I enable tracking in BTS 2006 I don`t seem to be able to do this from HAT as I did in 2004.
A: You can do this now through the Admin MMC Console. For example, if you need to be able to track properties of a custom schema, you can go to the schemas node under your application and go to the schema`s properties for tracking. Then at the corresponding receive or send port, you can enable document or property level tracking. For BizTalk context property tracking, you can click on the System.BizTalk application and follow the same guidance with the BizTalk property schemas.
