PIDX International publishes unit of measurement diagram

HOUSTON, June 02, 2022 (GLOBE NEWSWIRE) — PIDX International, with the support of its members, announces its new support for the UOM program guidelines.

The new standard was created to support PIDX trading partners seeking to identify the unit of measure (UOM) used in price sheets, invoices and transaction documents. These documents are exchanged frequently in procurement transactions throughout the energy industry supply chain, where units of measurement can vary widely and are made available free of charge. Enabling PIDX transactional documents to identify UOM can significantly improve transaction speed, accuracy, and efficiency, reducing delays and ambiguity in data exchange.

One of the key features of the UOM Program Support Guidelines is its backwards compatibility, which allows trading partners to maintain UOM Program support while minimizing changes.

“We’ve added the unit of measure schema at the price sheet header level to allow for ANSI, ISO, or UNECE validation,” says Margret Saniel, President of PIDX Standards and Guidelines and Head of Customer Service at FSO Portal. “To minimize the amount of changes, support for UOM in PIDX transaction documents has been added at the line item level, using the reference information indicator tag, thus only changing not the current schema layout, but increasing how reference data can be used to extend the usefulness of the PIDX standards. The updated schemas reflect these changes.”

The entire PIDX 1.62 schematic can be found here. The UOM schema support guidelines document the recommended support for identifying the UOM schema for price sheets, invoices, and transaction documents.
