What is EDI Mapping?

EDI mapping is a tool for managing multiple EDI standards within a single EDI system, and for translating EDI-specific standards into formats that other business tools can read and understand. Fundamentally, EDI mapping is a conversion process in which translation of data structures from a proprietary file (in csv format, txt, SAP IDoc, ERP-specific etc.) to an EDI mapping standard format (EDIFACT, ANSI X12 etc.) and vice versa. 

How EDI Mapping Works

Mapping EDI to ERP data structures are translated from an EDI standard format (EDIFACT, ANSI X12, etc.) to a proprietary file that can be easily ingested into a back end system (CSV format, txt, SAP IDoc, Flat File, or any ERP specific format).

  • As shown in the diagram, trading partner 1 uses Oracle ERP which uses a JSON internal format and trading partner 2 uses the SAP ERP system with IDoc internal format. To communicate a message to a trading partner 2, that JSON file needs to be converted into an EDI transaction and sent to a trading partner 2 using a standardized EDI Format like ANSI X12 or EDIFACT.


  • Now since trading partner 2 ERP uses iDoc for its internal format, the EDI file is converted into a iDoc file before being ingested into SAP ERP.


  • Mapping for EDI systems is bilateral so EDI providers like Commport, map the dataflow in both directions.
