How it works: Looks at every confirmed load (note contains #) whose anticipated completion lands on or before the Window To date and isn't fully built yet. For each trailer that isn't ready, it searches for a trailer with the exact same part number that becomes ready sooner — drawn from finished Stock, Unconfirmed loads, or Confirmed loads shipping later. Each physical trailer is offered as a donor only once, and loads inside your window are never raided to fix each other. Anticipated completion = last WO due date + 3 working days (Mon–Thu). These are suggestions — the actual unit/SO reassignment is done in GlobalShop.
