To add a conformed hierarchy to a fact schema you have two options:
Right click on the conformed hierarchy, select “add conformed hierarchy to…” and select the target fact schema
Drag and drop the conformed hierarchy directly into an open fact schema
In both cases, the system prompts you to choose the root aggregation level: according to your modeling requirements you can import the whole conformed hierarchy or part of it.
Once the conformed hierarchy is added to the fact schema, every change made to the conformed hierarchy (in terms of either structure or glossary) will be automatically propagated to the fact schema.
