Due Counts

The question: what is due to be counted? Every stocked pair whose last count — or, never counted, its last receipt or the day its balance appeared — is older than its counting interval, most overdue first: its ABC class, its interval, the basis date, and what it holds, with the unit of measure. The interval comes from the pair's own setting where one exists, else from its class — A 30 days, B 90, C 180 as seeded (§5.6). From here, counting starts: generate a count sheet for the warehouse — one draft count gathering the due products — or count a single product now. Pairs already covered by an open count are skipped by name, so the diary never sends two counts to the same shelf. The page also carries the Recalculate ABC classes action, which re-ranks every pair by the trailing year's issue value.
