Summary Supplier Engagement in Microsoft Dynamics 365 Supply Chain Management helps organizations connect supplier experiences, procurement processes, and business data in a single, extensible environment. Built on Microsoft Power Platform, it enables more consistent supplier management while providing the connected business context and governance needed to support AI and agent-driven procurement scenarios.

---

Giving suppliers better digital experiences shouldn’t require IT teams to create another disconnected system to manage. As organizations introduce AI and agents into business processes, that becomes even more important. Agents need access to business data and context, while organizations need to maintain the security, permissions, policies, and controls that govern how work gets done.

Supplier processes illustrate this challenge. Supplier information and interactions can span registration and qualification, sourcing, purchasing, invoicing, and ongoing supplier management. When those interactions take place across separate portals, email, and disconnected tools, organizations can end up with fragmented supplier information and additional integration and governance requirements. …

Private Preview: Dynamics 365 version 10.0.48 

Public Preview: Dynamics 365 version 10.0.49 

Disclaimer: The capabilities described here are in preview. Preview features are provided for evaluation only, are subject to change, and may not be released in their current form. Availability, timing, and functionality of any feature described here, including roadmap items and capabilities not yet generally available, are not guaranteed and should not be relied upon when making purchasing decisions. 

Inventory is often available, just not in the company where demand shows up. A customer may place an order in one legal entity while the best available stock sits in another. When that happens, teams often fall back on manual intercompany coordination, which slows fulfillment and adds operational cost. 

Cross-Legal-Entity Fulfillment Optimization in Dynamics 365 helps remove that barrier. By combining Distributed Order Management (DOM) with automated intercompany orchestration, the system can evaluate inventory across participating legal entities, help identify a suitable fulfillment location, and create the required transactions automatically. 

In practice, fulfillment decisions can be based on the right business signals, such as inventory availability, distance, cost, and sourcing rules, instead of being limited by company boundaries. …

Power BI Projects (PBIP) make reports and semantic models file-based, enabling source control, automation, and other developer workflows. You can edit those files directly in a code editor or through external tools. Until now, changes made outside of Power BI Desktop wouldn't appear until you restarted the application. With this update, Power BI Desktop detects those changes automatically, so there's no restart required.

Edit anywhere and see changes immediately

Power BI Desktop now detects changes made directly to PBIP files, regardless of whether those changes come from an editor, external tool, or automated process.

When a PBIP file changes on disk, Desktop detects the update and prompts you to reload the latest version of your project.

Apply external changes prompt in Power BI Desktop

Selecting Apply external changes reloads the updated files into Power BI Desktop without restarting the application.

This creates a much smoother experience when moving between Power BI Desktop and the tools you already use.

Open your project directly in Visual Studio Code

Power BI Desktop now includes an Open in VS Code option for PBIP projects.

Selecting it launches Visual Studio Code with the project folder already loaded as the active workspace, giving you immediate access to report and semantic model files.

Excel

• Use Python when Editing with Copilot in Excel [Windows, Mac, Web]

  Edit with Copilot helps you work with Python in Excel by executing Python code for advanced analysis, automation, and data transformation with results outputted directly in your workbook.

  Details:

  What changed: You can now use Edit with Copilot to perform advanced data analysis (statistics, simulations, advanced visualizations etc.) with your workbook data. Existing security and execution controls continue to help manage how code runs.

  Why: Python is widely used for data analysis, visualization, and automation. Bringing Copilot-assisted Python editing into Excel helps users move from intent to working analysis faster without switching tools.

  Try this:

  1. Open an Excel workbook with data you want to analyze.
  2. Open Edit with Copilot.
  3. Ask Copilot to complete a task like summarizing trends, cleaning data, or creating a visualization with Python.
  4. Review the output and inspect the results in Excel.

  Why this matters: This makes advanced analysis more approachable by pairing Python’s flexibility with Copilot’s assistance and Excel’s familiar workspace.

  Business impact: Teams can accelerate reporting, analysis, and repeatable data workflows in Excel, helping reduce manual effort and improve consistency.

  Personal impact: You can complete more advanced data tasks in Excel with Copilot’s help. …
