Every reservation is linked to a rate plan, whether it’s the rack rate or a discount code. Visual Matrix and your Channel Manager communicate through a mapping table that determines how information translates between the two systems. If the mapping is incorrect, it will prevent reservations from being processed. It’s essential to verify that the code is active and that the Market Segment, Referral Method, and Reason for Stay fields are filled out.
Path: Management > Interfaces > All Interfaces > select your Channel Manager > Select "Rate Plan Setup" in the toolbox on the right side.
