    ... I am required to use the cursor...

    Perfectly reasonable so long as this is homework. If not, then do it properly:

    UPDATE Outlet.tblProductMaster SET

    Product_Status = CASE

    WHEN Seller_No = @strSellerNo1 AND Product_Status = 'Available' THEN 'Removal'

    WHEN Seller_No = @strSellerNo2 AND Product_Status IS NULL THEN 'Available'

    ELSE 'UNKNOWN' END

    WHERE Product_No = @strProductNo

    AND Seller_No IN (@strSellerNo1,@strSellerNo2)
