Answer :
Definition: Electronic Data Interchange (EDI) is the electronic exchange of business documents (such as purchase orders, invoices) in a standardized format between organizations’ computer systems.
Processing of Purchase Order (PO) using EDI:
- Buyer creates a PO in their system.
- PO is converted into a standard EDI format (e.g., ANSI X12).
- EDI PO is transmitted electronically to the supplier’s system.
- Supplier’s system receives and processes the PO automatically.
- Supplier sends an EDI acknowledgment or invoice back to the buyer.
This process eliminates manual entry, reduces errors, and speeds up order processing.
