The FIX adapter supports FIX protocol versions 4.0 to 4.4.
By default, the Mapping Plug-in shipped with the FIX adapter does not support mapping nested fields from FIX to CEP, or from CEP to FIX. However, if you use the C8_FIXMsgBody column to send raw FIX messages, the nested fields will be preserved. Although the nested fields are preserved, you cannot modify the values of the nested fields using the FIX Adapter.
