  1. Which EDI transaction set is used by a retailer to send an advance ship notice (ASN) acknowledgment back to a supplier?

    Answer: EDI 997

    EDI 997 is the Functional Acknowledgment transaction set, confirming that a trading partner received and processed an EDI document such as an ASN (856).

  2. A WMS uses 'task interleaving' to improve productivity. What does this mean?

    Answer: Combining putaway and replenishment tasks into a single user trip

    Task interleaving directs workers to perform a complementary task (e.g., putaway) on the return trip after completing a pick, eliminating empty travel.

  3. In transportation management systems (TMS), 'load tendering' refers to:

    Answer: Officially offering a load to a carrier and receiving acceptance or rejection

    Load tendering is the formal process by which a shipper offers a shipment to a carrier, who then accepts or declines the load.

  4. Which WMS receiving process verifies that inbound quantities and item details match the purchase order BEFORE physically putting inventory away?

    Answer: PO-based receiving

    PO-based receiving requires workers to scan or enter item data that the WMS validates against the open purchase order before accepting the inventory.

  5. A company implements a voice-directed picking system. Which benefit is MOST directly associated with this technology?

    Answer: Hands-free and eyes-free operation that improves pick accuracy and speed

    Voice-directed picking frees workers' hands and eyes from handheld scanners, typically increasing pick speed and accuracy simultaneously.

  6. What is the function of a 'license plate number' (LPN) in a WMS?

    Answer: A unique identifier assigned to a handling unit that tracks it as a single entity through the warehouse

    An LPN is a serialized label applied to a pallet, tote, or carton that allows the WMS to track and move the entire unit without scanning each individual item.

  7. Which metric measures the percentage of orders shipped complete and on time without damage or documentation errors?

    Answer: Perfect order rate

    Perfect order rate captures all four dimensions of order quality—complete, on time, undamaged, and correctly documented—in a single composite metric.
