Matrix with two different tables with no common key

Hello everyone,

I want to create a matrix in PowerBI based on two tables that do not have a common key and I am grateful for any help/ideas.

 

Table 1 looks like this: 

 

Table1.png

As you can see, it contains a specific hirachy.

 

Table 2 looks like this (excerpt):

 Table2.png

As you can see, each category, subcategory and subsubcategory is a column on its own in Table 2.

 

The goal is to have all the categories, subcategories, and sub-subcategories from Table 1 with their respective hirachie as rows in the matrix, the customers (C1, C2, etc.) in the columns, and the values from Table 2 as the values. The result should look something like this:

I have created a PowerBI file with examplary data: PowerBi file 

 

Does anyone have a good idea how this solution can be archived? Any help is welcome. 🙂

 

Best regards,

Fabi

Result:

2. Create measure.

 

Flag =
IF(
  NOT( ISINSCOPE('Table'[Category])&&ISINSCOPE('Table'[Subcategory])) ,
CALCULATE(SUM('Table2'[Value]),FILTER(ALL(Table2),'Table2'[Customer]=MAX('Table2'[Customer])&&'Table2'[Attribute]=MAX('Table'[Category]))),
IF(
ISINSCOPE('Table'[Category]) &&ISINSCOPE('Table'[Subcategory])&&NOT( ISINSCOPE('Table'[Subsubcategory])),
CALCULATE(SUM('Table2'[Value]),FILTER(ALL(Table2),'Table2'[Customer]=MAX('Table2'[Customer])&&'Table2'[Attribute]=MAX('Table'[Subcategory]))),
IF(
ISINSCOPE('Table'[Category]) &&ISINSCOPE('Table'[Subcategory])&&ISINSCOPE('Table'[Subsubcategory]),
CALCULATE(SUM('Table2'[Value]),FILTER(ALL(Table2),'Table2'[Customer]=MAX('Table2'[Customer])&&'Table2'[Attribute]=MAX('Table'[Subsubcategory])))
  ,0)))

 

3. Result:

I implemented your solution and it works like a charme. However, I do not really really understand, how the filter part is working. Could you please describe it to me in words using this example: 

 

FILTER(ALL(Table2),'Table2'[Customer]=MAX('Table2'[Customer])&&'Table2'[Attribute]=MAX('Table'[Category]))),

 

Especially the parts with the MAX function are interesting to me since I always thought its only possible to compare integer values.

 

Best,

Fabian

 

This is a perfect solution to the problem. Very well explained. Thank you very much!
