Want to know about when we use x12 and when EDIFACT.
Is it necessary to use EDIFACT when we deal with european country.
There are no strict rules that all europians must use EDIFACT. Most of the Europian countries tend to use EDIFACT but it all depends on client requirements.
and for US clients mostly ANSI X12
Its all depends on business requirements and especially required when acquisitions happened.
ANSI X12- US
EDIFACT - EUROPE
