Summarize multiple columns based on values
I am stuck with an issue I cant seem to figure out how to do in DAX. Since users will select filters in PowerBI Services, I can't do this in Power Query/M as some materials would be filtered out and would require a change to the summary result table. Any assistance would be appreciated.
I have a set of data like below (but with many more rules & materials)
Material Rule-1 Rule-2 Rule-3
A Pass Fail N/A
B Fail Pass Pass
C N/A Fail Pass
And I want to create a table like
Status Rule-1 Rule-2 Rule-3
Pass 1 1 2
Fail 1 2 0
N/A 1 0 1
or it could be pivoted (rules down left and Pass, Fail, N/A across top) does not matter.
How would I accomplish this?

To unpivot a table using DAX is quite challenging. You may want to try the following steps in DAX to get your desired result.
1. Creating a new table with two columns, 'Rules' and 'Status'
new table = UNION(SELECTCOLUMNS(Sheet2, "Status", Sheet2[Rule 1], "Rules", "Rule 1"),SELECTCOLUMNS(Sheet2, "Status", Sheet2[Rule 2], "Rules", "Rule 2"),SELECTCOLUMNS(Sheet2, "Status", Sheet2[Rule 3], "Rules", "Rule 3"))You will be able to get a table like this:2. Then you can use a matrix format to display your result- AnonymousNot applicable
Sorry for confussion, but I need to create a summary table in DAX, because i am pushing to R which is limited to 150,000 rows and my data set is 3 million records and increasing. So, i cant use a widget (like a matrix) to summarize the data.

Hi Anonymous,
You can get it with the formula below. But this calculated table is relative stable, which means its values can't change as the filters or slicers change.
Table = ADDCOLUMNS ( DISTINCT ( UNION ( VALUES ( Table1[Rule-1] ), VALUES ( Table1[Rule-2] ), VALUES ( Table1[Rule-3] ) ) ), "Rule-1-num", CALCULATE ( COUNT ( Table1[Rule-1] ), FILTER ( 'Table1', 'Table1'[Rule-1] = EARLIER ( 'Table1'[Rule-1] ) ) ), "Rule-2-num", CALCULATE ( COUNT ( Table1[Rule-2] ), FILTER ( 'Table1', 'Table1'[Rule-2] = EARLIER ( [Rule-1] ) ) ), "Rule-3-num", CALCULATE ( COUNT ( Table1[Rule-3] ), FILTER ( 'Table1', 'Table1'[Rule-3] = EARLIER ( Table1[Rule-1] ) ) ) )
Best Regards,
