Hmm, I think vijrams meant "grouping of the accumulated sums" which will
require the PurchaseSum facts I proposed. Only then it is possible to obtain
all sums-per-day grouped by customer.

I don't see why "customers that purchased more than 100 on a given date"
should fire in Customer order.

Even with my solution some additional quirks will be necessary to get
the data grouped by Customer.
