I see you took my advice and reposted to the 2012 forum with the DDL. Good for you!
Now a few questions:
- Can a transaction qualify for the same event more than once?
- Do you allocate sales to the GroupIDs with the larger quantities first or the smaller quantities first?
- I am also unclear about the difference between GrpMinQty/GrpMaxQty and GrpSkuMinQty/GrpSkuMaxQty. Can you explain?
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
