Matrix with multiple hierarchy

[salemhaddad]

Hello,

I have a table that contains father_code and for each one of them there is a son code(it's like category and subcategory).

In parallel with, i have a corresponding label that corresponds to heach category. (It's like having Cateogry and subcategory and with it color and subcolor).

Note: The son code here is the first element as there is no father code for it.

Here is my table: 

Son_code	Father_code	Label
A		1
B	A	3
H	A	2
E	A	4
F	A	5
C	B	6
D	B	7

I tried using matrix to visualize the data but it does not work with double hiearchies as the first son code is not the real son code but the father code.

Here is a formatted table to understand the problem and how the output should show: 

	CODE	LABEL
+	A	1
-	A|H	1|2
-	A|B	1|3
-	A|F	1|5
-	A|E	1|4
-	A|B|C	1 | 3 | 6
-	A|B|D	1|3 | 7

If you have any idea on that either matrix or using DAX to format that.

Thank you in advance,

Salem

Hey salemhaddad,

Look into the PATH DAX function. Here's a link to some documentation. It seems to be exactly what you need.

It works by putting it as column and not a measure.

Thank you very much.

Thank you very much for the recommandation.

I tried to use it: 

DEFINE

  VAR path_column = PATH(table[Son_code], table[Father_code])

  EVALUATE

    SELECTCOLUMNS(table,table[Son_code], table[Father_code], 

"path_column", path_column

)

It give an error: A table of multiple values was supplied where a single value was expected.
