PBIP Issue: External TMDL Changes Not Applied Without Reopening Proj (PBI BI Desktop v2.149–Nov2025)

Hi jbarrosPT ,

The TMDL changes on the files directly are not live this can be seen in the considerations limitations of the PBIP format:

So ansewering your questions and my suggestion below:

• Is this a known bug or a current limitation of Project Mode?
  • This is a limitation of the PBIP project since and identified in the documentation
• Is there any way to force reload without closing the project?
  • The current option to update the Power BI Desktop file without closing and reopening are:
    • TMDL Viewer inside the desktop: this is a code editor that will allow for you to change all your model options and even some hidden ones directly on the Desktop in a Script format (https://learn.microsoft.com/en-us/power-bi/transform-model/desktop-tmdl-view)
    • Use the MCP server connected to Visual studio code this will allow for you to get updates directly in the desktop without reopening (https://learn.microsoft.com/en-us/power-bi/developer/mcp/mcp-servers-overview)
• Was the “Prompt to reload external changes” option removed in this version or hidden?
  • This prompt appears when you have a change in the Power Query syntax or table definitions DAX measure are not part of this prompt since the updates do not materialize on any data to your model but it's only a new definition
  • In this case it will appear different warning like Some table have incomplete or no data and the refresh button. After that you will get the correct result
