Lag-based snapshots in SAP IBP capture historical key figure values with a specified time offset (lag), useful for tracking past data (e.g., demand from 3 weeks ago). Their configuration and behavior are defined in SAP IBP’s time-series planning framework.

Option A: The number of lag-based snapshots are limited to nine levelsThis is incorrect. There’s no documented limit of nine snapshots in SAP IBP; the number depends on configuration and performance, not a fixed cap.

Option B: Lag-based snapshots are created in the Configuration app for a fixed time rangeThis is incorrect. Snapshots are configured in the Planning Areas app (via key figure settings), not a generic "Configuration app," and they dynamically adjust based on lag, not afixed range.

Option C: Target key figures for these snapshots are exposed to the user in planning viewThis is correct. Lag-based snapshot key figures (e.g., SNAPSHOT_LAG1) are visible and usable in planning views (e.g., Excel), allowing users to analyze historical data, per SAP IBP’s documentation.

Option D: Target key figures for these snapshots must have lag as a root attribute in the base planning levelThis is correct. The lag attribute (e.g., LAG = 1, 2) must be part of the base planning level (e.g., PERPRODLOCLAG) to store snapshot values distinctly, a requirement in SAP IBP’s snapshot setup, per official guides.

Thus, C and D are features of lag-based snapshots, per SAP IBP’s official functionality.
