When channels sell the same room in different ways (like packages or corporate rates), you can map all these versions to a single rate in your platform to simplify your rate management.
When to use multi-mapping
You can map multiple channel rates to one rate in your SiteMinder platform only when they refer to the same physical room type, when a channel sells different versions of the same room rate.
➕ For example, with Expedia, you might have one "Standard double room" rate in your SiteMinder platform, but Expedia sells this room in different ways:
Standard double room - SellRate - Hotel Collect
Standard double room - Package - Expedia Collect
Standard double room - Linked - Expedia Collect
Standard double room - Derived - Expedia Collect
You don't need to create new room rates for each of these in your platform, instead, map all these rates to your single "Standard double room" rate.
Remember: All rate types need to be mapped to reduce risk of overbooking and to ensure reservations are delivered correctly to your platform and connected PMS/RMS/CRS.
When to map rates individually
⚠️ Important: Do not map multiple channel rates to one platform rate if they represent different physical room types.
Incorrect multi-mapping can lead to overbookings, wrong pricing, and missing extras. You should map rates individually if they have:
Different room types: Never map a single platform room (e.g. "Double Room") to two different channel room types (e.g. "Double Room" AND "Twin Room"). The channel will assume you have double the inventory, causing overbookings
Different inclusions: Such as one rate including breakfast and another without
Different pricing structures: If the rates require different base prices.
Different availability requirements
$Map multiple channel rates to one rate$
Follow these steps for each channel rate you want to map to the single rate in your SiteMinder platform:
Go to Distribution > Channels tab.
Find your channel in the My channels tab.
Click the ellipsis button (three dots button) > select Edit room rates mapping.
In the Channel manager column, click on the rate to map.
Click the Map to button.
Click Yes for Start updating channel to begin updating rates, availability, and restrictions.
Select the channel rate from the Mapped to drop-down menu.
Click Save.
Repeat for each additional channel rate you want to map to this same platform room rate.
💡 For rates mapped to the same platform rate, ensure the pricing setup is Derived and set to Keep rates the same, as different prices or restrictions under the same rate can cause sync issues.
