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

|

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

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.
