The Overrides tab of the Trade Agreements window differs for inbound and outbound maps. For inbound maps, the window contains mailbox override information. For outbound maps, it contains both mailbox override information and override information for the receiver on outbound envelopes. For outbound maps, the Overrides tab is the same for X12 and HL7, but slightly different for EDIFACT.
Mailboxes are used for routing. They allow one pass of mapping to create multiple files. The ability to send data to multiple mailboxes eliminates the need for multiple passes over the data. Mailboxes allow you to send different messages for the same trading partner to different mailboxes. This is a capability that is often required by trading partners who have different functions in multiple locations. Mailboxes are also used to route (pass through) inbound messages to different internal mailboxes. For example, you might use this feature to keep test maps or compliance maps separate from production maps.
Mailbox information that you enter in the Trade Agreement window overrides information you enter in the Trading Partner window. (You can also override the use of this mailbox or the trading partner mailbox at runtime by clicking the Ignore Trading Partner Mailbox or Ignore Trade Agreement Mailbox check boxes on the Option 1 tab of the Run Inbound Map window.)
Outbound receiver information that you enter in the Trade Agreement window overrides information you enter in the Trading Partner window. This information is used to populate the outbound EDI envelopes.
