Detail area
The section of a transaction set that contains line item detail (e.g., quantity, price, etc).
Document
One complete business document (e.g., invoice, purchase order, etc.).
EDI standards
A published set of formats produced and controlled by either a national or international organization. Standards ensure EDI documents use the same file format.
Functional acknowledgement
A transaction set, which an EDI receiver returns to the sender to indicate that a transmission has been received and that the content of the transmission has been validated against the EDI standards. Functional acknowledgements have a built-in mechanism to ensure the recipient successfully received everything the sender intended.
Header area
The beginning segments of a transaction set which contain information that applies to all the information in the transaction set (e.g., invoice number, general sender, or receiver data).

Trading partners

Translation
The process of converting business documents from an application format to a standard EDI format for outbound documents and from a standard EDI format to an application format for inbound documents.

The national standards, which are used in North America, are controlled by the American National Standards Institute (ANSI).

ANSI also serves as the North American representative to the International Standards Organization. A group within ANSI, known as the Accredited Standards Committee (ASC), has a subcommittee simply referred to as the X12 subcommittee. The X12 subcommittee is responsible for EDI standards. Their purpose is to:
Element uses the ANSI ASC X12 standards for all of our EDI documents.
EDI standards are published by the Data Interchange Standards Association (DISA), a non-profit corporation that serves as the secretariat for ASC X12. Educational publications and actual EDI standards manuals are available from DISA.
