If Duplicate Value In Column vs Distinct Occurrence

Good evening Power BI Community!

In the Query Editor, I'm trying to create a new custom column to do the following:

If the data in Column A only occurs once in that column, then show me what is in Column D, if the data point in Column A has a duplication in that column, then produce string "Multiple".

Note limitation: Removing duplicates in Column A is not an option in our case.

What would you suggest I use as the DAX formula here?

Please advise? Thank you kindly,

Audrey

Hello and thank you everyone for your late night help!

It was definitely much appreciated. 😄

In case you're wondering, the approach I took that did the trick was as follows:

SOLUTION = IF (CALCULATE (HASONEVALUE(SOLUTION[COLUMNB]),ALLEXCEPT(SOLUTION,SOLUTION[COLUMNA]) )=TRUE,SOLUTION[COLUMND],"Multiple")

Thank you all and I hope you have a lovely weekend!

Hi,

Try this

=IF(CALCULATE(COUNTROWS(Data),FILTER(Data,Data[Heading1]=EARLIER(Data[Heading1])))>1,"Multiple",Data[Heading])

I have assumed that the Table name is Data and heading of column A id Heading1.  Also, the data type of entries in the heading column has been assumed as text.

Hey,

this DAX statement creates a calculated column in your table

```var whatsincolumnD =  'yourtable'[ColumnD]
return
IF(
CALCULATE(
COUNTROWS('yourtable')
,ALLEXCEPT('yourtable', 'yourtable'[ColumnA])
) >1
,whatsincolumnD
,"Multiple"
)```

Hopefully this is what you are looking for

Regards

Tom

Hello Tom,

Thank you for taking the time to respond!

I'm not familiar with DAX at all but am wondering, should I still use this formula even though I'm not trying to calculate anything?
