Why the Posted Sales GL Reports Slow Down in 9.0?

Users will experience a longer report compile time for the Posted Sales report in 9.0 or later. The reason this report will now take a longer time to compile is due to the changes we made in the routine to pickup the COGS at the time to the Inventory Issue instead of the time of posting. In these changes to make the transactions correct we now have to analyze 5 tables to get the information instead of only looking at one table.
