Diffrerence between llx_fournisseur_price>price and >unitprice

Hi

Can anyone tell me the difference between llx_fournisseur_price>price and llx_fournisseur_price>unitprice ?

I try to understand how to import Supplier price (Prix fournisseurs HT) and Minimum quantity price (Prix quantité min.) but can’t figure out the diffrence between them. Both are mandatory and reffers to llx_fournisseur_price>price and llx_fournisseur_price>unitprice

All the best

Hans
