Hi Set
Wow your query runs like a bat out of hell J 0.16 Milliseconds !! and it
easier to maintain as you say.
The only issue is that it somehow multiplies the totals by 6 on all results
as compared mine?
i.e. mine will return an invoice total of say 18500.00 and yours will return
111000.00
At first glance, your plan seems OK. However, it would be better if we also
could see the index definitions as well as get some information about index
selectivity. And, this list removes attachments, so please post the text of the

Hi, I'm looking at a system that I have not touched for some years and
wonder if there is a way to improve this code. This all works, but is
