EDI integration uses industry-specific standards and it supports multiple communication protocols. Before you start EDI Integration, it would be good if you have the following information ready:
1) EDI Standard. For example: X12, EDIFACT, etc
2) Communication Protocol: How are we going to retrieve the EDI document? Is it through FTP, local disk or AS2?
3) EDI Document version: For example: 4030. 4050, 5010, etc
4) EDI Document type: This is depending on the integration flow and the standard. Take X12 for example, 850 (Purchase Order), 856 (Shipment), 861 (Receipt), etc
