ANSI X12 Transaction Sets


An EDI document is referred to as a transaction set in the ANSI X12 standard.

The standards documents specify hundreds of different transaction sets, which are allowable documents in EDI.

The slide shows some of the more commonly used transaction sets. EDI professionals usually refer to documents by their transaction set number, rather than by name. So an EDI professional would refer to an 850, not a Purchase Order.

Note that certain transaction sets apply only to specific industries.
