I'll post the explanation of the problem by my colleague, which he gave me more than a year ago: The important thing to remember here is that this is about retail inventory cost valuation, and discounts at POS have no effect on cost, only retail revenue. He has The fifo_map is an associative container which uses the order in which keys were inserted to the container as ordering relation. In the graph, a rst mobile (the target) is moving with a known xed itinerary. "FIFO" stands for first-in, first-out, meaning that the oldest inventory items are recorded as sold first but do not necessarily mean that the exact oldest physical object has been tracked and sold.
