Data Element Dictionary |
|
The third tab in the ANSI X12 document is the Data Element Dictionary.
The code lists in the Data Element Dictionary are very long. Many of the element descriptions, like 98 - Entity Identifier Code - go for pages and specify hundreds of individual elements.
Most systems would use only a small subset of the available elements.
This is a crucial aspect of EDI system design - deciding which elements
are necessary and which are not.
