Purchase Order line currency conversion problem

I am creating a Purchase Order. The product Purchase/Cost currency is set as USD. When I add a PO line, the PO line price is automatically converted to EUR. How can I add a PO line in USD? I need to place a PO in USD, not in EUR. Please advise. Thank you.

Hello. the product is configure in USD ?

you can specify a price and a devise for a supplier.

Thank you! The supplier was in EUR…
