ConnectRE documentation currently shows which CORE fields map over to RE, but, there is no documentation to show which RE fields on the business relationship record "receive" information via ConnectRE and which fields do not. In the documentation, it shows that there are nine CORE fields that map over to RE fields. There are MANY more fields in a RE business relationship record - most are not "mapped" and do not "receive" information from Core via ConnectRE.
A full mapping guide would be extremely helpful.
