SAP Analytics Cloud (SAC) primarily focuses on providing business intelligence and analytics capabilities. It integrates with various data sources, including SAP HANA, SAP BW, SAP Universe, Excel, Google Sheets, and others, to create compelling stories and visualizations.

However, the ability to directly add multiple models from the datasphere to the same story might depend on the specific capabilities and updates that SAP has introduced since then. To get the most accurate and up-to-date information, I recommend checking the official SAP Analytics Cloud documentation or reaching out to SAP support or community forums.

Typically, in analytics tools like SAC, you can connect to different data sources and create datasets or models based on those sources. You can then combine and analyze data from these models within a single story or dashboard. If the direct integration of multiple models is not supported, you might need to create a consolidated dataset or model that combines the necessary data from different sources before building your story. This is a common practice in analytics platforms when dealing with data from diverse origins.

Please check the latest SAP Analytics Cloud documentation or consult with SAP support for the most accurate and current information on the capabilities of the platform.
