PATHITEMREVERSE DAX Function (Parent-child)

Returns the nth item in the delimited list produced by the Path function, counting backwards from the last item in the path.

PATHITEMREVERSE ( <Path>, <Position> [, <Type>] )
Parameter Attributes Description
Path

A string which contains a delimited list of IDs.

Position

An integer denoting the position from the right end of the path.

Type Optional

Optional. If missing or 0 then this function returns a string. If 1 then this function returns an integer.

Scalar A single value of one these types: integer, string.

Remarks

  • This function can be used to get an individual item from a hierarchy resulting from a PATH function.
  • This function reverses the standard order of the hierarchy, so that closest items are listed first, For example, if the PATh function returns a list of managers above an employee in a hierarchy, the PATHITEMREVERSE function returns the employee’s immediate manager in position 2 because position 1 contains the employee’s id.
  • If the number specified for position 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.
