Syntax
| Parameter | Attributes | Description |
|---|---|---|
| Path |
A string which contains a delimited list of IDs. |
|
| Position |
An integer denoting the position from the left end of the path. |
|
| Type | Optional |

Return values
The identifier returned by the PATH function at the specified position in the list of identifiers. Items returned by the PATH function are ordered by most distant to current.
Remarks
- This function can be used to return a specific level from a hierarchy returned by a PATH function. For example, you could return just the skip-level managers for all employees.
- If you specify a number for position that is less than one (1) or greater than the number of elements in path, the PATHITEM function returns BLANK.
- If type is not a valid enumeration element an error is returned.

Examples
-- PATHITEM returns the nth item of a path column, starting to count
-- from the beginning. It returns BLANK if no such element exists.
--
-- PATHITEMREVERSE starts to count from the tail.
--

-- otherwise certain levels are not visible. In this example, only 4 levels
-- are visible.

Parent-Child Hierarchies
DAX does not directly support parent-child hierarchies. To obtain a browsable hierarchy in the data model, you have to naturalize a parent-child hierarchy. DAX provides specific functions to naturalize a parent-child hierarchy using calculated columns. The complete pattern also includes measures that improve the visualization of ragged hierarchies in Power Pivot. » Read more
