In the Salesforce Consumer Goods Cloud (CGC) architecture, high-volume calculations and data processing for Trade Promotion Management (TPM) are handled by the Cloud Processing Service (CPS). This off-platform engine is necessary to manage the massive data grids involved in promotion planning.

When a System Administrator needs to interact directly with this engine---specifically to load, register, or sync external data sources (like 'Sell through volume') so they can be read as KPIs---they require specific privileges that go beyond standard CRM access. TheCGC Processing Services Registerpermission set license is explicitly designed for this administrative purpose.

This license grants the user the necessary API rights and access controls to manage theData Processing Engine (DPE)definitions and trigger the synchronization jobs that hydrate the CPS with data. Without this specific license, the administrator might be able to see the TPM application screens (if they have the TPM license, Option A), but they would lack the backend permissions required to configure the data ingestion pipelines that feed the calculation engine.
