For orders received electronically from another CAT Reporter, must the the Routed Order ID reported to CAT by the receiving CAT Reporter be in the exact format as which it was received from the sending CAT Reporter?
Yes. Routed Order IDs must be reported in the same format in which they were received or the audit trail will be broken. For instance, if CAT Reporter A routes an order with a Routed Order ID of AB_0001, the receiving CAT Reporter must also report a Routed Order ID of AB_0001. In this instance, a Routed Order ID of AB001, AB_001 or anything other than the exact format of the original Routed Order ID will cause the audit trail to break and the Route Event will be marked as Unlinked.
