Return values only if users don't belong to any group

[newpi]

I have the following table 

1	User name	User group	Output Column
2	User 1
3	User 1	Group A	Group A
4	User 1	Group B	Group B
5	User 2		User 2
6	User 3	Group A	Group A

Basically I want my output column to show groups or users only if they do no belong to any group. For example above.

User 1 has a null row in the 2nd line but User 1 also belongs to Group A & Group B. So in my output I do not want to have User 1 as value in the 2nd row . Similarly, User 2 does not belong to any group so I want to show User 2 as value in my output column.

@newpi , Try a new column like

Output Column =
var _1 = countx(filter(table,[User name] =earlier([User name]),[User group]))+0

return
switch( true() ,
isblank([User group]) && blank(_1)=0, [User name],
isblank([User group]) && blank(_1)>=0, blank(),
[User group]
)

Hi @newpi ,

Create a Calculated Column

Op Column = 
var a = CALCULATE(Count('Table'[User name]), FILTER('Table', 'Table'[User name] = EARLIER('Table'[User name])))
RETURN
IF(a = 1  && 'Table'[User group] = BLANK(), 'Table'[User name], 'Table'[User group])

Thanks @harshnathani this works. Only. 1 question though, I'm still trying to understand the formula but because of earlier function or anything else in the measure, is it necessary that all user 1 rows should be in sequence (row 2,3,4 here)? The same user can also be out of sequence right? meaning on rows (2,3 & 5).

Also is there a way to not show up blank in the filter slicer?

HI @newpi ,

Yes, it can be out of sequence.

To understand the EARLIER formula, please see this video.

Thanks @harshnathani The formula is also creating blanks (which we want it to) and grouping all user 1 under that blank and showing blank as a value in the slicer. Anyway to get rid of that?

Hi @newpi ,

Use the Visual Filter
