Count the number of related records

Hi, 

 

I am struggling with a calculation in DAX. I want to add the column "Children" to my dataset (I have one fact_Table, as displayed below). For example, ID 2 shows up twice under Parent and therefore has 2 children. So the number of times the ID value pops up in other rows is the amount of Children records. 

 

I used COUNTROWS and LOOKUPVALUE to no avail, I am hoping anyone here knows how to calculate this column. 

 

Fact_Table

ID

Type

Parent

Status

Children

Thank you in advance, 
Best,

Gijs

[Children] = // calculated column
var CurrentID = FT[ID]
var Result =
    COUNTROWS(
        FILTER(
            FT,
            FT[Parent] = CurrentID
        )
    )
RETURN 
    Result
