On the top part of the transaction mapping window, EDI standard data and application data are side by side - with source data on the left and destination data on the right. All of the data is presented in a tree structure that allows you to select a level to expose the level beneath - revealing data mapping, levels, rules, cross reference tables and conditions for EDI data and the record/table names for application data. In a tabular presentation at the bottom of the window, the Mapping section displays the data linkages and associated levels and rules as mapping takes place.
The Mapping section includes all of the segments in the transaction set or message you created, with each element displayed on a separate line. There are also fields for EDI data, such as segment, element, data type, and length; application data, such as record name, field name, and attributes; and trading partner data to be displayed as mapping takers place, as well as fields for levels and rules. As you map the source data to the destination data, each record and field of the application data appears on the appropriate line at the bottom of the window, next to the segment and element to which it is linked in the map. As you assign levels and add rules to levels or elements, these also appear on the appropriate lines in the Mapping section. (Refer to the Rules chapter for instructions concerning rules and the Map Flow chapter for instructions concerning levels.)
