Thank you for your reply. I will get the info together and post it, but most likely tomorrow (wife is on me to log off ☺ ). I did try your sum expression and when used, I lose the top 20 listing and everything is returned, though it does appear to calculate the MEM and when changed appropriately, the CPU quantities.
My apologies. I apparently started two threads with the same topic and did not mean to. My fault. I've solved my problem with Sunny's help. Here's the response I sent to Sunny in the other thread and again, my apologies. Not sure how I did that but I did.
Hello Sunny (and Anyone Else Following this discussion):
So, I've solved the problem, but it took you (Sunny) to point it out. In this case, I cannot have an item with three rows where the item_sku is the same. It just won't work. So, I eliminated the duplicate item_sku numbers, tweaked my calculated dimensions and expressions and viola! I'm now getting what I was after which was a top 20 listing by quantity to include the associated CPU and Memory quantities.
Many thanks to Sunny for pointing out the conflicts I had between the calculated dimensions and expressions.
Sunny, I will mark your last response in that regard as the correct response, As always my friend, thank you for your assistance. It's always appreciated. Happy Holidays!
