Problem defining appropriate measure in report - powerbi

Question

The table below indicates a minimal example of my raw data:
Product
Order Day
Customer
Units Ordered
Units Delivered
P
Apr 1
X
4
3
P
Apr 2
X
4

P
Apr 1
Y

R
Apr 4
Y
2
0
R
Apr 5
Z
8

R
Apr 6
Z

Based on this I am able to create the following table as a PBI report where I give a product summary:
Product
# diff. Customers Ordered
Total Ordered
Total Delivered
Service Rate
Product-level Service Test
P
3
14
8
0.57
1
Q
2
6
3
0.5
0
R
3
17
14
0.82
1
This final column in the above summary checks whether more then 50% is being delivered. This report can be filtered on Order Day (time filter) as well as Customers.
Now, in a similar fashion, I would like to create a customer summary report:
Customer
# diff. Products Ordered
# Products Passing Service Test
X
2
1
Y
2
0
Z
3
1
W
1
1
It basically summarizes the product report after filtering for specific customers. My problem is the final column called "Products Passing Service Test". I am not able to define an appropriate measure in order to get the right numbers displayed in this column. I tried some other approaches but then it does not work well with the time filter on Customer Orders.
Anyone that can help? Thank you very much!
