A hierarchical schema is an asset that defines the expected hierarchy of data. The schema is based on a sample or schema file that you upload in Data Integration.
You can use a hierarchical schema in a Hierarchy Builder transformation or a Hierarchy Parser transformation. You can create the hierarchical schema as a standalone asset or within the transformation. Whether you create the schema as a standalone asset or within a transformation, you can associate it with any transformation.
After you create a hierarchical schema, you can edit it to change the root or the schema definition. You can't edit or delete a hierarchical schema if it's used in a transformation.
