DAX Parent & Child – PATHITEM Function

PATHITEM DAX function returns the item at the specified position from a string resulting from evaluation of a PATH function. Positions are counted from left to right and it comes under Parent and child functions.

Refer similar post:- PATH DAX, PATHCONTAINS DAX, PATHLENGTH DAX

Syntax:

PATHITEM(<path>, <position>, <type>)

Description:

1	path	A text string in the form of the results of a PATH function.
2	position	An integer expression with the position of the item to be returned.
3	type	(Optional)An enumeration that defines the data type of the result: 0-Results are returned with the data type text. (default). 1- Results are returned as integers.

Note:

This function can be used to return a specific level from a hierarchy returned by a PATH function.
This function does not support the Direct Query mode.

So let’s start with an example, sample dataset format as below:

Table Name – EmployeeData

EmpId	Dept	EmpName	Parent Id
1	Manager	Sandeep Raturi
2	Team Lead	Antonio Moreno	1
3	Team Lead	Aria Cruz	1
4	Team Lead	Dinesh Raturi	1
5	Developer	Matt	4
6	Developer	Jhon	4
7	Developer	Jacobs	2
8	Developer	David	3
9	IT Support	Jack	2

In above dataset we have EmpId, Dept, EmpName & Parent Id columns, and Parent Id column contains Employee manager Id.

Follow these steps-

Step-1: Create a new calculated column for PATH and write below DAX code.

Path = PATH(EmployeeData[EmpId],EmployeeData[Parent Id])

Step-2: Create another calculated column for PATHITEM and write below DAX code.

PathItems(Level-2 Emp)= PATHITEM(PATH(EmployeeData[EmpId],
EmployeeData[Parent Id]),2,1)

See the output:

PATHITEM DAX

You can see in above screenshot, we have provided second position to fetch employee manager that are at level 2.

If you want to see level 3 positions –

PathItems(Level-3 Emp) = PATHITEM(PATH(EmployeeData[EmpId],
EmployeeData[Parent Id]),3,1)

See the final output-

PATHITEM DAX Level-3
