Notice

When selecting a concept from the dtimbr schema, by default, the preview data won’t show if the concept has 3 relationships or more. This configuration in Timbr is intended to avoid executing all the JOINS of a table. The configuration can be changed to allow any number of relationships to show. After loading the dtimbr concept, all the relationship properties will appear normally and when used will show the data.
