Originated--people who came to the store to shop.
Fulfilled--anything that was bought online (DU, OPU, SFS, STS).
Comp--comparable sales. So, total comp would be how well your store did overall compared to last year. You can also look at Originated comp or Fulfilled comp.
DBO's at our store are told to be most aware of Month to Date comp sales to determine how well they're doing. At my review, I was told that I needed to comp up 5% by my next review. Considering that I had comped up 18% for the last one, I'm not really too worried.
