On outbound maps, you control the levels. On inbound maps, the standard controls the levels. EDI standards group segments into different tables, or levels. The levels you define and assign in ECMap should be based on the EDI standard for the transaction being mapped.
For both inbound and outbound transaction maps, levels are assigned to EDI segments from the transaction Mapping window.

Choose Build>Mapping from the main menu.
The Mapping window displays.
