Let's just say that reading the corresponding topic in the SP2 CHM was a disheartening experience. No, let's say more than that. The process of lifting content from another topic into this one disemboweled the RTM version of the first topic while not providing a very enlightening introduction to the FX reporting system in this one.
I hope TMM redresses the balance to some degree.
LONG way to go.
