updateHierarchyLevel mutation to modify an existing hierarchy level. This mutation uses partial update (PATCH-like) semantics: only the fields you provide are updated; omitted fields remain unchanged.
Access policy:
- The API user context must have permission to update hierarchy levels.
- A hierarchy level with the provided
idmust exist. - If
parentIdis provided and is not0, a hierarchy level with this ID must exist.
To keep the current parent, omit
parentId. To move a level to the top, set parentId to 0.
