TRADACOMS Messages
The TRADACOMS standard encompasses 26 messages. Each message is laid out in a hierarchical structure. Unlike EDIFACT, TRADACOMS does not use a single message format, but instead uses multiple messages.
A single order message could comprise an Order Header Message (ORDHDR), multiple Orders Messages (ORDERS), Order Trailer Message (ORDTLR). Multiple individual order messages can repeat between the ORDHDR and the ORDTLR.
In the general case, a TRADACOMS transmission consists of:
-
A Start of Transmission Segment (
STX) -
One or more files
-
A Reconciliation Message (
RSGRSG) -
An End of Transmission Segment (
END)
A TRADACOMS file consists of a series of messages. Each message has a similar overall structure, beginning with a Message Header Segment (MHD) and ending with a Message Trailer Segment (MTR). The contents, however, are different for each transaction type or File Format (for example, Orders, Invoices).
