This article will show why you should choose the "Standard" rate plan when mapping your rate plans for Expedia.
Background
Myallocator can only update one "rate" for each of the channels. Since we can only update one Rate Plan, you should always choose the "SellRate S" rate plan when mapping Expedia.
That way, we send the regular rate for the Standard Rate, and the other plans/packages can be derived from the Standard Rate Plan.
Examples
On the example below, you can see that the Rate Plan chosen for the Standard King Room was "Best Available Rate", which is incorrect
Instead, you should always choose the "top" rate plan selection which will be designated as "SellRate S" - check below the correct option for the Standard Two Queen room type
Once you have changed the Rate Plan selection, send a full refresh to update Expedia extranet
