GauVendi differentiates between 3 types of room products: 

1) RFCs - Detailed Room Inventory

2) ERFCs - Virtual Room Products

3) MRFCs - Standardized Room Products

MRFCs are a copy of the classical and simplified room types mirroring the PMS room types. Each physical room of a hotel is linked to one MRFC only and one RFC. Each room can be linked to numerous virtual room products (ERFCs).
