Electronic Data Interchange (EDI)
EDI is the computer-to-computer exchange between two companies of standard business documents in electronic format. EDI replaces the paper document with a transfer from one computer to another of electronic data.
EDI is the preferred method for processing purchase orders and invoices. Union Pacific has an ongoing program to assist suppliers in implementing EDI (Electronic Data Interchange).
It is the Supply Department's responsibility to assist suppliers in determining Union Pacific requirements for EDI transactions, and to notify suppliers of the schedule for Rail Industry Guidelines updates.
It is the supplier's responsibility to contact appropriate Union Pacific personnel for assistance and to comply with the schedule for Rail Industry Guidelines upgrades.
