What is meant by Reuter field BOOK_STATE is Compatible

mktdata

Hello,

We are suing RFA 8.1 C++ api and MarketPrice(MP) domain to get Level1 data. Reuters data model suggest that Field BOOK_STATE(FID - 6516) is "compatible" and show it to be "Optional". What does it mean? It will be available on certain markets only? if so, can I know which markets publish this field?

Also as shown in Red circle, clicking mouse over "<<" suggests that "field is backward compatible". What does that mean?

Thanks for reaching out to us.

I checked the Data Model Discovery – User Guide and couldn't find the explanation of those options.

Please contact the Data Model Discovery support team directly via MyRefinitiv to get answers.

Hello, As shows in attached screen shot, I can see those fields in data model discovery of MP domain. You have to turn on "Show compatible" as shown in screen shot
