Countif in DAX or Power Query

Hi all,

 

Please help as i was not able to find solution for what i require.
I have dataset with repeating ID number and i need to count how many times it repeats in a dataset. Groupby does not work, as i need data to remain ungrouped.

 

My goal is to count how many ids i have that apear more thatn one time in a table. Preferably i would like to do it in DAX, but if i can create this calculation in power query, i will be able to easily do it in DAX.

 

Below is example of dataset i have.

Any help is greatly appreciated

    If all you need is a measure for a card that displays the count of IDs that appear 2+ times, that should be pretty easy.  I'm not sure why you're so against using summarization or groupings for a single measure, but here's how I would do it:

    CountMultiIDs = COUNTROWS(FILTER(ADDCOLUMNS( VALUES('Table'[ID]), "IDCount", CALCULATE(COUNTROWS('Table'))), [IDCount]>1))

    The tricky bit here is to use CALCULATE around the inner COUNTROWS so that the DAX re-evaluates the context at which it is counting.

      Thank you mussaenda,

       

      This will give me total count of ids, where i need to filter distinct ids that apear in list more than once.

       

      From table provided, result should be 2 :

      IDs 1 and 2 apear more thatn once in a dataset.

       

      Hope this makes it clearer

        Power BI groups the ID though you choose do not summarize.

        As a workaround, I used an index to prevent it from grouping then counted the ids.

    How about this?

     

    = CALCULATE(
	COUNT(Table1[ID]),
		FILTER(Table1,
			Table1[ID] = EARLIER(Table1[ID])
		)
	)

      I tried using this, but for some reason, EARLIER does not recognise any column name.

        That's something strange.

        This is the output returned by that formula....
