Sorry to interrupt, but can we please stay on track here, this is about Nebbers!
Excuse my lack of SQL but is this just a trial? I was thinking more ALL of the credit-value based MMs so 1000 10000, 25000 etc and for both Projects and SubProjects and with a tolerance of somewhere about 0.1% either way. It may seem like a lot to do but I feel there will not be many of them so perhaps it won't take too long, though if it does, then by all means drop the idea. Cheers
