What is regarded as the main building block of reports in OneStream?

The main building block of reports in OneStream is considered to be cubes. Cubes in OneStream serve as multidimensional structures that store data in a way that provides efficient access for analysis and reporting. They are designed to include various dimensions that categorize and provide context to the data, enabling complex queries and calculations to be executed efficiently.

Cubes allow users to perform in-depth analytics by combining data across various dimensions such as time, entity, and account, making them pivotal for generating comprehensive reports. They act as the foundation upon which reporting structures are built, ensuring that users can derive meaningful insights from the data stored within.

In contrast, entities refer to organizational units or sections of the data model, dimensions categorize or group data in the cubes, and workflows automate processes within OneStream, but they do not serve as the foundational reporting structure like cubes do. The effectiveness of reporting in OneStream is primarily driven by the design and usage of cubes, illustrating their significance as the core component in the reporting framework.
