EDI GTIN Efficient Process Management

All levels of the packaging hierarchy should be identified with a GTIN. For inventory management, it is essential that the different levels of the packaging hierarchy are known in the system so that conversion factors or minimum stock levels can be defined. It is critical to understand not only how the GTINs being exchanged relate to the items and hierarchies, but also the capabilities of trading partners to use GTIN for each applicable transaction type (e.g., purchase orders, invoicing, rebate/sales tracing, payment remittance, etc.).

Align your product hierarchy from all available units of sale to applicable systems (e.g., EMR, MMIS, WHS, etc.). Identify the preferred/default Unit of Measure (UoM) for ordering and determine whether conversions from other UoMs will occur on the buyer’s side before the PO quantity is calculated or on the seller’s side once the order is received.

  • If on the seller’s side, determine how the buyer may override default conversions if a nondefault order UoM is truly required.
  • If UoM can be converted/overridden by the seller, the buyer should have mechanisms in place to adjust their receiving and invoicing to the converted UoM.

Confirm within the trading partner relationship how GTINs relate to existing product numbers. Cross-reference other product identifiers used throughout the system. Determine if the cross-references have been validated against the GDSN or another mechanism such as EDI. More about GS1 standards.
