Paperless (electronic) exchange of trading documents, such as purchase orders, shipment authorizations, advanced shipment notices, and invoices, using standardized document formats

• A. Electronic data interchange (EDI)
• B. Drum schedule
• C. Distribution inventory
• D. Dock-2-stock

Answer: (A)

Electronic data interchange (EDI) is the paperless exchange of trading documents between trading partners using standardized formats. It allows documents such as purchase orders, shipment authorizations, advanced shipment notices, and invoices to be transmitted directly between computer systems, enabling automatic data capture and processing. The standardized formats ensure different systems interpret the data consistently, reducing manual entry, errors, and cycle times, and improving speed and accuracy in procurement and order-to-cash processes. The other terms describe operational concepts not about electronic document exchange: a drum schedule is about production pacing, distribution inventory refers to stock held in distribution centers, and dock-to-stock concerns receiving goods into stock.
