I had a note from Andy in the US field who asked about this but also sent a solution. If you click on the Open Sales Orders, Shipped but not invoiced Sales Orders and a few other links. See screen shot below
You might get this error
Andy suggested the solution was to apply Hotfix Rollup 4 for AX2009 SP1 and SP3 for SQL2005. So if you need to use these links then it worked for Andy
It will take a little while to apply these do you VM so we’ll be applying them to the up-coming Refresh 3 VM.
