calculated colum to see if a an account has contacts with a certain role or not

[BartStruyf]

Hello,

I'm struggeling to get this answer. 
My customers have mulptiple contacts, with different roles.  I want to summurize in a column if a customer has a contact with a certain rol or not.  
I have one table with :

Account ID	Rol	HAS A?
1	A	Y
1	B	Y
2	A	Y
2	C	Y
3	B	N
3	B	N

I don't know how to write the right DAX-formula.

Thansk for you help,

Bart

// T is your table.

[Has A?] = // calc column
var __account = T[Account]
var __hasA =
	NOT ISEMPTY(
		FILTER(
			T,
			T[Account] = __account
			&&
			T[IDRol] = "A"
		)
	)
RETURN
	if( __hasA, "Y", "N" )

I agree it is better to right a measure when you can.  But also here is an expression for your calculated column.

HasA = if(calculate(Countrows(YourTable), All(YourTable), YourTable[Rol]="A", YourTable[Account ID]=Earlier(YourTable[Account ID]))>0, "Y", "N")

If this solution works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.

Hi @BartStruyf,

First of all, I would not recommend to use calculated column for this task. A measure would be more appropriate.

But to solve your problem you might do the following.

If you don't have separate dimension table for Roles you need to:

1. Create a measure [Num of unique Roles]: = DISTINCTCOUNT('YourTable'[IDRol])

2. Create a calculated column: = CALCULATE([Num of unique Roles];filter(VALUES('YourTable'[IDRol]);'YourTable'[IDRol]="A"))>0

Hi @razmochaev

And what if he wants to be able to slice by these values? Would you recommend a measure in this case as well?
