Creating a Data Quality Dashboard filtered by multiple criteria

[tgie]

Hello,

I am trying to create a Data Quality Dashboard filtered by multiple criteria. I have the following two tables:

Error-Table:

uid	product	attribute
1xxxx	Product 1	Attr1
2xxxx	Product 2	Attr1
3xxxx	Product 1	Attr3

where the product column is joined from the next table:

All-Products-Table:

uid	product
1xxxx	Product 1
2xxxx	Product 2
3xxxx	Product 1
4xxxx	Product 1

I want to display the quality of each attribute in a bar chart. But when I calculate the quality in a new column or table, I can no longer filter by product.

Using the example from the table above:
Attr1 occurs twice in the Error-Table for a total of 4 records in the All-Products-Table. The rel. error is 2/4 = 50%.
By using a filter I want to take a closer look at Product1:  Now Attribute1 occurs once in the Error-Table for a total of 3 records in the All-Products-Table. The error would now be 1/3 = 33.3%.

What is the best way to solve this problem?

Hi @tgie ,

According to your description, here are my steps you can follow as a solution.

(1) My test data is the same as yours.

(2) We can create a measure. 

Measure = 
 var _countrows_allpro=COUNTROWS(ALLSELECTED('All-Products-Table'))
 var _countrows_attribute=CALCULATE(COUNTROWS('Error-Table'),FILTER(ALLSELECTED('Error-Table'),[attribute]=MAX('Error-Table'[attribute])))
 return DIVIDE(_countrows_attribute,_countrows_allpro)

(3) Then the result is as follows.
