Hi!
The first action I have in my table, is to check the number of values in Table 1 - Line 1 are equal within the Table 2, I am using the formula =SUM (COUNTIF (B12:P12; B3:P3)), as it is in the link "Image 1"
After this process, I need to count how many times we had 11, 12, 13, 14 and 15 equal values, for this process I use the formula =COUNTIF (R12: R25;"=11") in a new column in Table 1
In summary, I need to individually check the rows/cells of table 1 in table 2 and count the number of times the result is 11, 12, 13, 14 and 15, with the final result, 5 additional columns in table 1 with these values comparing against all the rows in table 2.
Can you help me on how to do this on PowerBI?
Solved! Go to Solution.

Here you are. This is a solution with viewer rows. The rows of T1 and T2 are converted to lists contaning all the (column) values. Next I have made a query with a Cartesian of the row indexes of the rows (= lists) of T1 and T2. With a List.Intersect and a List.Count the numer of matches are determined.
The last step in Power query is to build a table with the match counts.
Finally the matrix is constructed in DAX.
Good luck!

see the Pbix in the link:

Here is the outline of the solution:
Unpivot Table1 and Table2
Per table construct 3 columns Line/Column/Value
Cartersian product between T2 and {1..5}
Merge Cartesian with T1
Look where values are equal (then 1 else 0)
Groupby line T2 and Catesian with T1 and aggregate SUM equals ( 0 or 1)
Caterian Groupby with {11..15}
Compare Groupby with {11..15}
Power query steps are ready. Apply model to Power BI and construct the matrix…
… and Bob’s your uncle!
Good luck,

Heelo @JW_van_Holst.
First of all, thank you very much for your help.
But, my tables are very large and these actions are not being completed via PowerQuery, I have 3,268,760 rows in table 1 and 2186 rows in table 2, which keeps growing every day (only table 2).
I would like to know if there is any simpler way of obtaining this result, on a small sample base in Excel, which I would carry out, as in the attachment, but I can't import and work my complete base in excel.
Can you help me again?
