SSR Correction In our blog post on November 6 (http://watsonwalker.com/two-red-alerts/) and our Tuning Letter 2015 No. 3, we incorrectly specified the default status of SSR as disabled.  The default is actually for it to be enabled if the associated Space Constraint Relief data class function is enabled.  We’ve corrected the blog entry, but you may…
