DATEDIFF with condition

[JavidRobatian]

Hi experts, hope you all doing good.
I have two tables in Power BI called Date and Invoice that are related with (invoice[date] 1:* Date[Date])
Now I'm trying to Calculate DateDiff with below condition:
1- The user not use slicer, in this case:
DateDiff = date[invoice] - today()
2- The user select the month using the table:
For example if user select 11 in month slicer:
DateDiff = date[invoice] - 11/01/2023
thank you help me to Calculate DateDiff with up condition.

Hi, @JavidRobatian 

try below

Measure = 
var a = SELECTEDVALUE('date'[month])
var b = DATEDIFF(CALCULATE(min(invoice[date]),ALLEXCEPT(invoice,invoice[cu nu])),TODAY(),DAY)
var c = DATEDIFF(CALCULATE(min(invoice[date]),ALLEXCEPT(invoice,invoice[cu nu])),DATE(2023,a,1),DAY)
var d = IF(ISFILTERED('date'[month]),c,b)
return
d

HI, @JavidRobatian 

in your previous post DATEDIFF between DATE column and User SELECT Date 

you mention smallest number for each customer thats why i use min if you want latest date then you can use max()

with same formula select month(11) below result in image 

with same formula select month(10) below result in image 

in above output is some diff in output

beacuse i am take your previous post data

Try this measure: Make sure you add a Year slicer

Datediff = 
    IF(
		ISFILTERED( 'Date'[Month] ) , 
		INT( MAX( 'Date'[Date] )  - MAX( Invoice[Date] ) ),
		INT(TODAY() -   MAX( Invoice[Date] ) )
	)
