In Cell B1 I want to sum the unique values in Column B per product in Column A.

B1 = 700 + 300 + 200 + 700

Currently, in Cell B1 I use the formular from this question which is =SUM(UNIQUE(B2:B9)).
However, with this formula I get 1.200 as result because it does not include the 700 from Product_D.

How do I have to modify the formula so it sums up the values unique per product?

Try SUMPRODUCT instead.

=SUMPRODUCT(B2:B9/COUNTIF(A2:A9,A2:A9))

It will get you the sum of values in B for unique values in A.

Note: this is assuming,the values in B2:B9 are all numeric. If not you will get a #VALUE error

As you have UNIQUE() function then you can use it with index and sum like-

=SUM(INDEX(UNIQUE(A2:B9),,2))
