How can extensibility be used?

• A. By Scenario Type and by cube
• B. By Scenario Type and by time
• C. By cube and by time
• D. By Scenario Type and by an individual member

Answer: (A)

Extensibility in OneStream is configured to run at the intersection of a specific Scenario Type and a specific Cube. This pairing defines where the custom logic applies and what data it can access, so you can tailor behavior to that particular planning scenario and its data model. For example, you could implement a validation or data transformation that only triggers when the Forecast scenario type processes data in the Sales cube.

Time and individual members aren’t used as the primary scope for extensibility settings, so the extensibility framework targets the combination of Scenario Type and Cube. This approach keeps the extension tied to the relevant planning context and data structure, rather than applying it globally or to arbitrary time slices or members.
