This question is related to a simpler problem, posted here: Calculating % by Dividing Filtered Matrix Columns in MS Power BI
Given: There are 2 (or more) attributes (e.g. 'Date' and 'Location') rather than just 1 (e.g. 'Date'), on which the tables have to be connected. In this case, both tables have to be filtered by date, as well as location, as in the following example:
Table 4:
Date_1 Location_1 Numerator
01-Jan-19 NY 5
05-Feb-19 CA 4
04-Apr-19 WA 1
07-May-19 OR 3
11-Jun-19 ND 5
22-Jun-19 NY 4
25-Jul-19 MN 5
31-Aug-19 NY 1
03-Sep-19 NY 4
25-Oct-19 MI 5
Table 5:
Date_2 Location_2 Denominator
03-Jan-19 NY 7
05-Jan-19 NY 9
16-Feb-19 CA 8
22-Feb-19 CA 7
04-Mar-19 AZ 10
18-Mar-19 ND 8
24-Apr-19 WA 8
25-Apr-19 WA 8
01-May-19 OR 10
10-May-19 OR 8
04-Jun-19 ND 8
08-Jun-19 NY 7
03-Jul-19 MN 8
18-Jul-19 MN 6
23-Aug-19 NY 10
31-Aug-19 NY 9
03-Sep-19 NY 9
20-Sep-19 NY 7
03-Oct-19 MI 7
27-Oct-19 MI 6
Tables 4 and 5 can be pivoted to get something like the following:
Table 4 Pivot:
Sum of Numerator 2019 Months
Jan Feb Mar Apr May Jun Jul Aug Sep Oct Location Total
Location
CA 4 4
MI 5 5
MN 5 5
ND 5 5
NY 5 4 1 4 14
OR 3 3
WA 1 1
Total 5 4 1 3 9 5 1 4 5 37
Table 5 Pivot:
Sum of Denominator 2019 Months
Jan Feb Mar Apr May Jun Jul Aug Sep Oct Location Total
Location
AZ 10 10
CA 15 15
MN 14 14
ND 8 8 16
NY 16 7 19 16 58
OR 18 18
WA 16 16
MI 13 13
Total 16 15 18 16 18 15 14 19 16 13 160
The desired output is as follows:
Table 6:
2019 Months
Jan Feb Mar Apr May Jun Jul Aug Sep Oct Location Total
Location
CA 38.46% 38.46%
MN 35.71% 35.71%
ND 0.00% 62.50% 31.25%
NY 31.25% 57.14% 5.26% 25.00% 24.14%
OR 16.67% 16.67%
WA 6.25% 6.25%
Ttl 31.25% 26.67% 0.00% 6.25% 16.67% 60.00% 35.71% 5.26% 25.00% 38.46% 23.13%
Problem: The % calculated in Power BI is wrong, when the data are visualized in Matrix format similar to Table 6. I thought that Tables 4 and 5 could be linked with connecting them all on 'Location' and 'Date' attributes by using unique calendar and location lists. However, this does not work, because "Ambiguous paths..." error is generated when trying to connect Table 4 and 5 with calendar table, each on 'Date' attribute, and also Table 4 and 5 with location table, each on 'Location' attribute.
Question: How can one obtain correct results as in Table 6 in Power BI, using the equivalent of Tables 4 and 5?
