Need help finding duplicate Id's

DoubleTap — Thu, 04 Apr 2024 20:20:16 GMT

I think i have a relatively easy ask but im going crazy. I have a table where i need to count the duplicate Id's. I create a simple count measure [ ID_Cnt=count(Id) ] then created another measure to identify the dups [ Duplicate_Cnt = if(ID_Cnt > 1), 1 , 0) ]. It just adds up all the Id's as if the condition wasnt even there. I would like to be to have the total number of duplicates associated with the ID and one measure that has the total count of all overall dups.

Any help is appreciated.

Here is an example of the data and my desired output:

Duplicates = 5

Data	ID	Date	Result	ID	Dups
	1	1/1/2021		1	1
	9	1/2/2021		2	2
	2	1/3/2021		4	1
	4	1/4/2021		7	1
	7	1/5/2021		9	3
	9	1/2/2021
	9	1/2/2021
	2	1/3/2021

Duplicates = var aaa = ADDCOLUMNS(VALUES('Table'[ID]), "count id", CALCULATE(COUNT('Table'[ID]))) return IF( HASONEVALUE('Table'[ID]), SUMX(aaa, [count id]), SUMX(FILTER(aaa, [count id] > 1), [count id]) )

EDIT - misread the requirements, have changed the calculation. The above is my attempt. I hope it helps!
