Reason Codes
The following is a list of all reason codes used by CFE. These reason codes are used in a variety of contexts (order cancellations, order rejections, etc.). All reasons are not valid in all contexts. The reason code will be followed by free-form text. The specific text the system delivers may vary from the test listed below, to provide clarification of the reject reason. CFE may add additional reason codes without notice. Members must gracefully ignore unknown values.
