Description / Problem Statement

Microsoft 365 Copilot has access to Microsoft 365 tenant data through the Semantic Index, but Dynamics 365 Business Central data is currently excluded.

Business Central contains highly valuable business data such as customers, vendors, items, sales documents, financial KPIs, and operational insights. The lack of native integration significantly limits the usefulness of Microsoft 365 Copilot for business users who rely on Business Central as their core ERP system.

Proposed Solution

If a native integration between Business Central and the Microsoft 365 Copilot Semantic Index is not feasible in the short term, Microsoft should provide a default, out‑of‑the‑box Microsoft Graph / Copilot connector for Business Central that:

• Can be enabled by administrators with minimal configuration
• Indexes relevant Business Central entities securely and permission‑aware
• Integrates directly into the Microsoft 365 Copilot Semantic Index
• Works with Microsoft 365 Copilot Chat at the same performance and intelligence level as other M365 data sources

Why Copilot Studio Is Not a Sufficient Alternative

While it is technically possible to access Business Central data using Copilot Studio, this approach has several major limitations:

• Query performance is significantly slower compared to the Semantic Index
• Responses are not as context‑aware, intelligent, or reliable
• Prompt execution is inconsistent and often does not follow instructions correctly
• The experience is clearly inferior to Microsoft 365 Copilot using the GPT‑5.2 model
• Higher implementation and maintenance effort for customers

As a result, Copilot Studio does not provide a comparable user experience to Microsoft 365 Copilot with native Semantic Index access.

Business Value

A native or default connector would enable scenarios such as:

• “What are our current open sales orders and risks?”
• “Summarize overdue customers and their outstanding amounts.”
• “Which items have low availability and high sales volume?”
• “Give me a financial overview for this month based on Business Central data.”

This would dramatically increase the value of both Business Central and Microsoft 365 Copilot for decision‑makers and operational users.

Summary

Business Central is a critical system of record and should be treated as a first‑class data source for Microsoft 365 Copilot.

A native integration or an official out‑of‑the‑box connector for the Semantic Index would unlock enormous productivity and insight potential for customers.
