Using filter to compare two columns and count Rows from a category

[Anonymous]

Hi Everyone, Beginer here in Dax .

I have a Table as below .

ID	Policy Number	Policy Sequence	Master Sequence
123456	2121W	1	3
123456	213445	2	3
123456	4153	3	3
21345	XVw1C	1	2
21345	XVCE	2	2

My Table looks like Above , I would need to pick rows in this way after the filtering

and do the count of those rows that are filtered.

IDeal table

ID	Policy Number	Policy Sequence	Master Sequence
123456	4153	3	3
21345	XVCE	2	2

I can't seem to figur out exactly what need to be done in the filter.

My query is as below.

" CALCULATE(",

" DISTINCTCOUNT('Policy'[Policy Master Number]),",

" 'Policy' [Master Sequence] = 'Policy' [Policy Sequence]",

I know this should work in Sql and give a single row but i get this error when i try to do it this way to filter sigle row .

The expression contains multiple columns, but only a single column can be used in a True/False expression that is used as a table filter expression."

Any Help here would be greatly appreciated .

Hi @Anonymous ,

You could try to add a filter in measure like below to see whether it work or not

Measure 2 = CALCULATE(MIN('Table (3)'[Master Sequence]), FILTER('Table (3)','Table (3)'[Policy Sequence]='Table (3)'[Master Sequence] && 'Table (3)'[Policy Number]=MIN('Table (3)'[Policy Number])))
Measure = CALCULATE(MIN('Table (3)'[Policy Sequence]), FILTER('Table (3)','Table (3)'[Policy Sequence]='Table (3)'[Master Sequence] && 'Table (3)'[Policy Number]=MIN('Table (3)'[Policy Number])))

Perhaps create a new column like:

Column = IF([Policy Sequence] = [Master Sequence],1,0)

Then just filter on Column = 1

Thanks for the Quick Response , Is it possible to create a column from the set on the run time and filter the rows.

The reason i'm asking this, we are using this as an cube XMLA rather than a Power Bi Front End.

I would have to write a measure .
