How to group (Blank) relations in the Power Bi Desktop App

I have a pie chart that shows groups of a certain category (in my case groups of status).


As you can see, there is a option named "(Blank)". I want to assign these blanks to one of my groups instead of them showing seperately, as can be seen here for example (see the answer of @v-huizhn-msft in Why there is a (BLANK) option for my new grouping in Power bi). However, in my case, Power Bi doesn't list Blank ones in the ungrouped values - in a nutshell: I can't assign the Blanks to a group. 


My theory is, that the issue might lie within the Blanks not being empty fields but nonexistent relations in my case. I don't have  a column "Status" in the same table, but in a related table and not every dataset has a related one in the other table (where the Status field is). 


Is there a way to group datasets where the relationship is "blank"? Have I missed to adapt a certain property?

And if it is not possible: do you have an idea what a clean way to solve this issue would be?


Even after extended research I couldn't quite figure it out and would be really thankful for some help :). 


Here is my case in more detail, if you need more information to grasp the issue: 

The data model looks something like this (simplified for this question): 


The relationships active in both directions: 


For my pie chart I counted the Elements of the right table by Status groups: 


I created and edited these groups like this (see "New group" and "Edit group")



This is the resulting pie chart: 


As you can see there is a new Category named "(Blank)" that I want to assign to group 2. 

But as you can see in the Edit-view of the groups, there is no blank option to be assigned to one of the groups.

Hello, I found a solution, you just create a new group from the group you already created and it will appear the blank as one of the variables to group 😄

I would also like to know the answer to this.  In my case, I have two values, "Member" and "Non Member", but I also have blanks resulting from transactions where the person does not have a full record telling us whether they are a member or not.  For these blanks, I would like to group them with the non-members.  If this is not possible, does anyone know if it has been put forward as an idea to be upvoted?

Is there a solution for this? I also do not see the blank values when i try to group them. But then they emerge as a seperate group in the report.

Hi @Butterfly ,

Go to Filters pane and select "is not blank" in the field of the group (Filters on this visual).


If I have misunderstood your meaning, please provide more details with your desired output and pbix file without privacy information.

Hello @v-rongtiep-msft

thank you for your time and effort! 

However, I do not want to ignore the blank datasets, like you would do by filtering for "is not blank", since that would distort the graphs statement, but rather, as I said in my question, include the blank ones in one of the groups, so that they are not listed seperately. But when I edit the groups, there is no "blank" that I can assign to the group of my desire. 

Do you have any ideas, on why that is and how to best cope with this issue?
