We make a lot of use of summary WRS cross tab reports which are then linked to detailed WRS reports.

This enables users to run a summary report, and then click on a value and drill to the detailed transactions that make up the total.

One of the issues with this in WRS 3.1 (SAS 9.1) is when a user clicks on a sub-total within the WRS report they often drill to a blank report or a report that doesn’t show valid transactions for the summary value.

We eneded up having to train our users to never click on a sub-total to drill down.

There is a usage note at http://support.sas.com/kb/40/708.html that describes when drilling down on sub-totals will and won’t work.

Good to know when this is going to happen, but of course what is missing is the link to a hotfix that makes it work properly, aaarrrggghhhh.  Of course it is fixed in SAS 9.2 / WRS 4.2 I believe.
