If your PMS stores rates in a different currency but you need to send rates to Booking.com in another currency (e.g., Euro - EUR), you can use the "Convert Rates" feature in the channel mapping. To enable currency conversion:
Go to app.zeevou.com and click on Listings.
Open your desired Listing.
Click on Manage Channels in the top right.
Click on the key icon next to Map in front of Booking.com.
Click on Hotel ID.
In the Currency dropdown, select the currency required by Booking.com (e.g., EUR Euro).
Tick the checkbox for Convert Rates.
Save the settings.
