Measure to exclude rows based on multiple columns

See this approach by creating the measure and applying filter:

Multiple Rows Project ID = 
var _a = CALCULATE( COUNTROWS(), ALLEXCEPT( 'Table', 'Table'[Project ID], 'Table'[Market]))
RETURN IF(_a > 1, 1, BLANK())

Optional: Create another measure to know the count

Count Rows Project ID - Market =  
CALCULATE( COUNTROWS(), ALLEXCEPT( 'Table', 'Table'[Project ID], 'Table'[Market]))

Hope it helps!

Hi Vishruti 

Here is another measure / example.

Flag = 
	MAXX(
		ADDCOLUMNS(
			SUMMARIZE(
				'ProjectsData',
				[Project ID],
				[Market]
			),
			"__Cnt", CALCULATE( DISTINCTCOUNT( 'ProjectsData'[Parcel Types] ) )
		),
		[__Cnt]
	) > 1

It will return TRUE for any combinations that have more than 1 Parcel Type.  If there is only 1 Parcel Type then it will return FALSE.

Let me know if you have any questions.
