How to show all the tables in the model as a list of fields and count blank values within that ?

[YashGurudath891]

Hello All,

I am trying to find a way to list all the tables existing within a PowerBI model as fields and then count the blank values within each of those tables. (It can include the all the blank values from all the fields within each table).

Something like this :

Table Names	Count of Blank Values
Table 1	10
Table 2	20
Table 3	15
Table 4	6
Table 5	7

Thanks in Advance

Hi @YashGurudath891 ,

First, create a new column for each table as the table name.

Then create a new table with all table names as one column.

Finally, create a measure to calculate the number of blank values for each table.

Measure = SWITCH(TRUE(),
            MAX('Table'[Column1]) in VALUES(Table1[Column]),
            CALCULATE(COUNTROWS(FILTER(Table1,ISBLANK(Table1[Column2])))),
            MAX('Table'[Column1]) in VALUES(Table2[Column]),
            CALCULATE(COUNTROWS(FILTER(Table2,ISBLANK(Table2[Column2])))))

This solution is perfect. But, I am not looking for blank values in just one column. I want to look for blank values throughout the table (if there are over 20 cloumns). Do I have to repeat that for every column ? Is there a better way .

Thanks alot for this.

@YashGurudath891 what you mean blank values if a table has 10 columns, do you want to check the blank value in a column? Not sure if checking the blank value in a table makes sense, maybe I'm missing something.
