Essentially, EDI (Electronic Data Interchange) validation is the automatic process of finding and rejecting errors in an EDI document. Because EDI documents are used in business transactions, there are rigid regulations and guidelines in place. That way, each party has the same information in the same format.
EDI validation is a vital step in EDI transactions. By verifying that a document has no syntax errors and that it is standard-compliant, the 2 or more trading partners involved in a transaction will have more accurate data (and fewer misunderstandings and delays).
