I am building a catalog for Einstein Email Recommendations and I need to merge data from different countries. I know that I need to have localized fields for Regular Price Display and Sales Price Display and that in these fields I also need to insert the currency symbol.
Do I also need to have localized fields for Regular Price and Sales Price?
Moreover, if I have two different countries, can I map data regarding one country to standard fields (e.g. ProductName) and data regarding the other country to localized fields (e.g. locale_xx-XX_ProductName)?
Finally, do I need to use the xx-XX format for localizations or can I also use a different format, such as xxXX? Using this one I already see these fields as locale fields in the Einstein Catalog.
