In Salesforce Consumer Goods Cloud TPM, the behavior of Key Performance Indicators (KPIs) within the planning grid is governed by the KPI Definition, specifically the Edit Mode property. This property dictates where and how a user can input data.

The requirement here is specific: the Key Account Manager (KAM) must provide a manual input (Writeback) for the discount, but this input is restricted to theTotalcolumn (the aggregate for the promotion duration) and mustnotbe allowed in the weekly/periodic columns.

Edit Mode: Total (Option B):This is the correct configuration. When set to "Total," the cell in the Total column becomes editable. When the KAM enters a value (e.g., $10,000), the calculation engine automatically distributes (disaggregates) this amount across the weeks and products based on a defined reference profile (like Baseline Volume). The individual weekly cells remain read-only or are overwritten by the distribution logic, preventing the user from manually "tweaking" specific weeks which could break the distribution logic.

Edit Mode: All (Option A):This would allow editing inboththe Total column and the individual weekly cells, violating the requirement.

Editable Storage Level (Option C):This defineswherethe data is saved in the database (e.g., at the Tactic level vs. Product level), but it does not control the UI behavior of locking the weekly columns while allowing the Total column to be edited.
