Power BI measure not matching data view

[Anonymous]

So I have a BI Measure that shows the percentage.

This is the measure:

Cost blank =
VAR __AmountBlank = CALCULATE(COUNT(X[Cost]), X[COST] = BLANK())
VAR __Total = COUNT(X[Cost])
RETURN
DIVIDE(__AmountBlank, __Total, -1)

The variable __AmountBlank returns the value 382 965.
When I go to the data view, and filter Cost on blank it returns 2 753 records.

I also tried ISBLANK(X[COST]) and X[COST] = "" (this returns an error) but nothing works.. 

How do I resolve this issue?

Hi @Anonymous 
Please the below formula for count of blank rows. Take measure

Count =

Var A= COUNTROWS('Table')

var C= COUNTBLANK('Table'[Doc])

Return Divide(C,A,-1)

This worked! Thanks a lot!

HEllo @Anonymous ,

try

VAR __AmountBlank = CALCULATE(COUNTROWS('TableName'), X[COST] = BLANK())

Interesting, did not try this yet! Unfortunately it does give the same result as the previous one..
