In the SAP Analytics Cloud modeler, Dimension Groups are used to organize the list of dimensions into logical categories or folders. This feature is particularly useful in complex models with numerous dimensions, as it enhances readability and simplifies model management. By creating groups, modelers can logically structure dimensions (e.g., by business area like "Sales," "Finance," or "HR"), making the model easier to navigate and understand. This capability is part of the modeling experience for both live and acquired data models.

A. Level-based hierarchy: Incorrect. This organizes members within a single dimension into distinct levels (e.g., Country, State, City), not the dimensions themselves into categories.

C. Value driver tree: Incorrect. This is a specific visualization widget used within stories for what-if analysis and simulations, not a feature for organizing dimensions in a model.

D. Parent-child hierarchy: Incorrect. This defines relationships between individual members within a dimension to create a hierarchy, but it does not organize the dimensions themselves.

select (Add Group) to create a new group. Then you can drag and drop dimensions into the group." This documentation explicitly describes the use of "Groups" to organize dimensions.

2. SAP Help Portal - About the New Model in SAP Analytics Cloud: This document confirms that the new modeling experience

which includes dimension groups

is available for live data models. "The new model is available for both acquired data and live data from SAP HANA and SAP S/4HANA."
