# Official sources

Use this reference only when you need source grounding for Dynamics 365 Commerce behavior or omnichannel retail operations.

## Microsoft Learn documentation

Use these as starting points, not as proof of the user's live channel configuration, pricing setup, or Commerce Scale Unit health:

- https://learn.microsoft.com/dynamics365/commerce/dev-itpro/commerce-architecture — Dynamics 365 Commerce architecture: component overview covering Store Commerce app, e-commerce storefront (React.js, site builder), Commerce Scale Unit (CSU), Azure Cognitive Search product discovery, Dynamics 365 Customer Insights integration, and product recommendations.

## Certification alignment (verify currency)

- Exam MB-340: Microsoft Dynamics 365 Commerce Functional Consultant — verify current status and skills measured at learn.microsoft.com/certifications before citing. Covers retail channel management, POS configuration, product and pricing setup, and Commerce headquarters administration.

## Terminology note

The Store Commerce app replaces Modern POS (MPOS) as the primary in-store POS application. Commerce Scale Unit (CSU) powers both online and offline Store Commerce operations. Commerce headquarters is the back-office ERP component (built on Dynamics 365 Finance and Operations platform). Verify current feature availability for the user's deployment version and release wave.

## Grounding rule

Official documentation explains Commerce behavior. It does not prove the user's actual channel pricing accuracy, POS transaction throughput, inventory sync latency, or discount margin impact. Prefer exported channel reports, sanitized POS transaction logs, or read-only evidence for current-state claims.
