On the inbound transaction Mapping window, you can perform EDI element to field mapping actions by either:
Highlighting an element and using the Map menu,
Right-clicking an element and using the top part of the drop-down list.
You have the same mapping choices on both menus. You can:
Map an element to a field in a record, to a memory variable, or to a special memory variable called a conditional variable.
Repeat the mapping of an element or choose to not map (or ignore) an element.
Have ECMap automatically create an output field based on an element – at the same time that the element is being mapped to the newly created field.
