Hello, all...I am thankful you exist. 🙂
Here is my issue:
I am trying to do a pie chart that compares number of arrests where a mental health flag is present vs. when it is not.
I have duplicate rows if the arrest was for a person who had more than one type of flag.
Currently, I am using Count(Distinct) in the visualization filter so that an arrest is only considered once, however, it is counting one "Yes" and one "No" for each arrest number.
What I am looking for is a way in DAX to have the first instance of a duplicate that meets a condition say 'Yes' and any following values be blank if they are the same arrest number. That way I can filter out the blank values.
I currently have a simple IF statement: IF(table[column] = "MH", "Yes", "No") which returns:
Arrest # | Flag | MH Flag |
1 | MH | Yes |
1 | HXS | No |
1 | FEL | No |
2 | FEL | No |
3 | HXS | No |
I would like a DAX expression that returns the following based on the duplicate arrest numbers (Thank you so much in advance!):
Arrest # | Flag | MH Flag |
1 | MH | Yes |
1 | HXS | (Blank) |
1 | FEL | (Blank) |
2 | FEL | No |
3 | HXS | No |
Solved! Go to Solution.
Please try
MH Flag =
IF (
"MH"
IN CALCULATETABLE (
VALUES ( 'Table'[Flag] ),
ALLEXCEPT ( 'Table', 'Table'[Asset #] )
),
IF ( 'Table'[Flag] = "MH", "Yes" ),
"No"
)
tamerj1,
You are a genius beyond measure. It worked. Thank you so much!!
