Disaggregation in SAP Analytics Cloud (SAC) refers to how values entered at a higher level in your data model—such as totals or parent members—are automatically broken down and applied to lower-level (leaf) members. It enables top-down planning by letting you enter a single value and have SAC spread it to the relevant details underneath.
What’s the Difference?
| Approach | Manual Entry | System-Driven |
|---|---|---|
|
How it works |
You input values directly at a detailed (leaf) level |
You enter values at a parent or aggregated level and let SAC split them |
|
User control |
Full control over each individual value |
Controlled by SAC logic or planning panel settings |
|
Use case |
You know the exact values to enter |
You’re estimating or setting a total that needs to be broken down |
Manual Entry
Manual entry means entering values directly into leaf members in a planning table.
- You choose exactly what goes where
- Ideal for precise, bottom-up planning
- Used when specific input is required for each product, cost center, or region
Example
- You type in 200 for Product A, 300 for Product B, and 500 for Product C. These values are not derived—they’re intentional.
Tip
- Use manual entry when you’re working with highly granular input or when you want to override automated logic.
System-Driven Disaggregation
System-driven disaggregation kicks in when you enter data at a parent level, and SAC automatically determines how to spread it across child (leaf) members. SAC uses rules and historical data (if available) to guide the split.
- Equal: Distributes evenly across children
- Proportional: Uses existing values to define the ratio
- Weighted/Input: Set in the Planning Panel
- Blocked: If disaggregation is prevented by locks or validation rules
| Use Manual Entry When… | Use System-Driven Entry when… |
|---|---|
|
You want full control over each value |
You’re doing top-down planning and want to save time |
|
You’re entering data for bottom-up reporting |
You’re forecasting at a summary level |
|
Precise data input is required (e.g., from departments) |
You’re modeling what-if scenarios or allocating targets |
