# `[>]`

The `[>]` operator allows a temporary parent to be created from a sequential range of elements within a flat hierarchy.

This is commonly used with date dimensions or ordered lists.

## Example Flat Hierarchy

Hierarchy name: `Date List`

```text
2026-01-01
2026-01-02
2026-01-03
2026-01-05
2026-01-06
2026-01-07
2026-01-08
2026-01-09
...
```

The following expression:

```text
Date List»2026-01-01[>]Date List»2026-01-04
```

creates a temporary parent containing the below elements:

* `2026-01-01`
* `2026-01-02`
* `2026-01-03`
* `2026-01-04`

## Common Use Cases

* Date range reporting
* Rolling periods
* Custom time aggregations
* Dynamic subsets of flat hierarchies

## Notes

* `[>]` works only on ordered flat hierarchies.
* The range is inclusive of both start and end elements.
