Procurement Notices communicate sourcing opportunities, requirements, and conditions from buyers to potential suppliers. Typically sent by a purchasing organization or procurement authority to vendors or supplier networks, this transaction set may be issued in response to supplier inquiries, as part of a competitive bidding process, or as a proactive market notice. Key segments include the BCO (Beginning Segment for Procurement Notices), which establishes the notice type and general parameters; the CTP (Pricing Information) segments, which specify pricing terms and conditions; and the PO1 (Baseline Item Data) loop, which details individual line items with associated quantities, measurements, and item-specific terms through nested segments like PID (Product/Item Description) and DTM (Date/Time Reference).

Consider a manufacturing corporation, ABC Industrial Supply, that issues a procurement notice to qualified vendors regarding upcoming demand for precision fasteners. ABC Industrial transmits an 836 transaction set to its approved supplier network, including company names and contact information in the N1 loop, baseline item details and quantities in the PO1 loop, delivery dates and lead time requirements via DTM and LDT segments, and payment terms through ITD. Vendors such as XYZ Fastener Company and Premier Hardware receive the notice, review the opportunity details—line item specifications in PID, required quantities in QTY, and any restrictions in CTB—and prepare quotations or confirmations in response.
