In my current project, invoice files were generated from logistics system in the XML format which is transformed to EDIFACT format EFACT_D01B_INVOIC_EAN011 in BizTalk before sending it to the customer.
The customer has given a new requirement to send invoice files in ANSI X12 format through Ariba network.
I wanted to know the equivalent ANSI X12 field for corresponding EDIFACT field.
The below link gave me fair idea of X12 and EDIFACT differences and equivalents
The above document and comparing with X12 and EDIFACT implementation guide provided by the customer was helpful in creating mapping with X12 standard.
