Symptoms

The AVR caching mechanism fails to store dimension-based queries properly, which leads to incorrect reports.

Impact

Reports will be incorrect.

Conditions

Using AVR caching mechanism (turned-on by default).

Workaround

Using the following TMSH command should solve the problem: tmsh modify sys db avr.requestcache value disable * NOTE: the above might cause AVR to perform a bit slower.

Fix Information

The system no longer stores the dimension-based queries in the AVR cache.
