When a scheduled incremental data refresh starts, which operations are disabled?

• A. All reporting is disabled.
• B. Data loads from external sources are blocked.
• C. Ad hoc data refresh for functional areas is not possible during a scheduled data load.
• D. User login is blocked.

Answer: (C)

During a scheduled incremental data refresh, ad hoc refreshes for functional areas are blocked to prevent overlapping updates. This keeps the data flow serialized, avoiding conflicts, partial updates, or inconsistent states that could occur if a manual refresh runs at the same time as the scheduled job. The system ensures the scheduled load completes in a controlled, coherent state before allowing any on-demand refreshes again.
