Update order category codes from new sheet rows

When new order rows lack category codes your warehouse can't route items and fulfillment stalls. This fills codes automatically so orders are routed correctly ahead of the next fulfillment run.

Overview

Missing category codes force warehouse coordinators into manual lookups and slow fulfillment. This flow tags new order rows automatically and updates the sheet so inventory and operations staff can route and pick orders reliably ahead of the next fulfillment run.
