Shortage.
Quantity arriving under what was expected. Catch it before the trailer leaves, or it becomes a claim instead of an observation.
Reference · Receiving automation
Receiving automation is a sequence of small decisions: which steps a machine can carry, which stay with a person, and what happens the moment something doesn't match. Get the sequence right and the dock runs the way it already runs, with a record behind it. This is the map, from trailer at the door to receipt closed out.
The working definition
Ask three vendors what receiving automation means and you'll get three answers: conveyor and robotics, a paperless workflow, or scanning without anyone lifting a reader. Only the last one changes what receivers do all day. A step is automated when its data gets captured correctly without a person stopping to produce it, and it has to fail open: if the capture layer stops, the receive still finishes by hand.
Before automating anything, walk one inbound trailer end to end and note where an error stays invisible for weeks, then fix identity first: trailer, door, and purchase order. A perfect scan attached to the wrong PO is worse than no scan, and most of this automates well since appointment scheduling and the advance ship notice already carry the data. What stays human is the check-in judgment: a carrier outside its window, a seal that doesn't match. See dock door scanning for how that assignment carries through the unload.
The capture step
This is the step everyone means by receiving automation. Automated capture removes the aiming, not the reading: cameras positioned along the path pallets already travel read labels as pallets come off, and nobody changes route or stops. See camera barcode scanning at receiving for the setup, and the barcode and label cheat sheet for what the barcode types carry.
Single-SKU pallets match against the advance ship notice as pure arithmetic; mixed pallets and repacked material stay closer to human hands. One honest limit applies here, including to us: a scan is what triggers the record, so a label that never reads produces no automatic capture, which is why the exception path below isn't optional.
The exception path
Automation doesn't reduce exceptions. It surfaces them earlier, in higher volume, because errors that used to be absorbed quietly now have a system noticing them.
Quantity arriving under what was expected. Catch it before the trailer leaves, or it becomes a claim instead of an observation.
Extra material arriving. The mismatch most likely to be waved through, and most likely to turn into inventory variance nobody can explain.
A condition call, not a data call. A camera can flag the obvious cases, but whether the material is acceptable stays a person's decision.
A label that won't read, or disagrees with its human-readable line, drops the pallet out of the automated path and into someone's hands.
The rule across all four: an exception should stop the record, never the freight. The pallet keeps moving; the receipt gets flagged. The full procedure for documenting each type is in receiving discrepancy documentation.
The supervisor and the metrics
Review stays scoped to exceptions, happens while the evidence is still fresh, and treats corrections as additive: the original captured value stays alongside any change, with who made it and when.
The steps that produce data reliably: matching a trailer to its door and purchase order, reading labels as material comes off, matching counts against the advance ship notice, and posting the closed receipt. The judgment calls, like whether a seal discrepancy is a problem, stay human.
Not entirely. Label reads and quantity matching remove most routine counting on single-SKU pallets. Mixed pallets, repacked material, and anything without a readable label still need hands and eyes.
By flagging the record and letting the freight keep moving. An exception should capture what was expected and found, the trailer, door, time, and an image where one exists, then route to the supervisor while the material is still stageable.
Per handling unit: the label read, item and quantity, purchase order, door, capture time, and an image. Per receipt: every exception and correction, and who made it. Capture time should be set by the device and never edited.
Flowtally reads the label as the pallet comes off the trailer and keeps the picture with the read and the exact time. Clean receipts post themselves. Exceptions go to the supervisor on shift with the evidence already attached.
