I will let you ponder if you need to reticket all, or just the reordered product, wether a stack can have multiple ticket (a white one say 5 from the last and one red one two from the back know wether you need an urgent order) etc...
And whether or miracle, if you don't receive any ticket a week that you don't need to reorder !
It's amazing how if that was expressed in term of resource allocation, reference counting, tagged pointers, scaling heuristic, garbage collect... that would click in people's mind, but many are incapable at abstracting because they feel they are beyond this.
