In each row, the two columns at far left uniquely identify the schema definition in this row:
Table rows are sorted according to the numbers and characters in the Category column.
Each value in the Name column is a link. When clicked, this link displays a table that outlines the EDIFACT document structure in this schema definition, showing all of its segments and fields. You can click on any of the links in this display to drill down for more details about any item. InterSystems IRIS extracts these details from the .SETS, .SEGS, .COMS, .ELMS, and .CODES sections of the SEF file that you import to define the structure of this EDIFACT document.
