This scenario addresses a common data granularity mismatch: the Planning is done at the Parent (Anchor) level, but the Data (Base Volumes) resides at the Child (Sub Account) level.

To bridge this gap, thePromotion TemplateandAccount P&Lmust be configured forAggregation.

Select Sub Accounts on Account P&L:The Key Account Manager must essentially "opt-in" the relevant sub-accounts into the view. This tells the systemwhichchildren contribute to this plan.

Calculation Mode: Sub Account Aggregation:This is the specific setting in the Promotion Template that dictates the engine's behavior. Instead of looking for a baseline volume record attached directly to the Parent Account (which doesn't exist in this scenario), the engine is instructed to look at the selected Sub Accounts, retrieve their individual baselines, andsum them up(Aggregate) to display the total at the Planning Account level.

Without this "Sub Account Aggregation" mode, the baseline at the planning level would likely show as zero because the system would default to looking for a direct match at the parent level. Option B correctly identifies the combination of UI selection (P&L) and calculation logic (Aggregation Mode) required to surface this data.
