If the company (usr) has ever viewed or bought items in the product category (item), then the recommendation column contains the value in the prod_preference column of the user table; otherwise, the column contains the recommendation score calculated by the function.
If the recommendation value is greater than 0 and the company has never viewed or bought items in the product category (that is, the value in the prod_preference column of the user table is 0), then the new_reco_flag is 1, meaning that the product category is to be recommended to the company.
