Security in Consumer Goods Cloud TPM operates on two layers: the standard Salesforce record access (Sharing Rules) and the application-specific TPM User Settings.

For the complex requirement of "selecting specific combinations of elements" (e.g., User A handles 'Beverages' for 'Walmart' but only 'Snacks' for 'Target'), standard Salesforce Sharing Rules are often too blunt or require excessive maintenance. TPM addresses this viaUser Settings.

In the TPM application configuration, you can defineManaged AccountsandManaged Productsfor each user or user profile. This acts as a filter for the Planning Grid (P&L view). When a Key Account Manager (KAM) logs in, the system checks these User Settings to determine which part of the massive Product x Customer hierarchy to load into their view. This ensures they only see and plan for the specific intersection of Customers and Categories they are responsible for. Option A correctly identifies this mechanism ("User settings") as the standard and intended way to handle this granular, matrix-based responsibility assignment within the TPM module, rather than relying solely on broad Platform security or Permission Sets.
