Rate Inquiry XML tag for preferential rate

Summary

Rate Inquiry XML tag for preferential rate

Content

we are using 'Remote Query - RIQ' to fetch rates from OTM (to Oracle EBS). Oracle has provided standard Remote query xml to fetch rates. It does have xml element to fetch the preferential rate like - <IsPreferred></IsPreferred>, This is ONLY allowing values like Y or N, but when we look at Rate Inquiry at User Interface level it has the drop down values - 1. Do Not Use the Preferred Rates 2. Preferred Rates only 3. Preferred Rates If Available.

Issue here is -
Calling rates using Remote Query, we can only use <IsPreferred></IsPreferred> - Y or N, what value to be used to fetch rate inquiry result with UI options
