Cannot load model

[schaema3]

Hi,

we're using the Microsoft Power BI cloud to host our reporting platform. Recently the data model of a report got replaced with a new data model. Before this happened I re-pointed my file to the new data model. Now when I digged out an older report (that still pointed to the old data model) I got this two error message:

It is possible to close the left error message and get re-pointed to the SQL Server Analysis  Servces database. When I'm fixing the connection (with going through internal authentification process), the Power BI report doesn't re-point to the changes I just entered but falls back to the old database (that no longer exists). The eror that now pops up is this one:

It now turns into an endless loop. Neither the Retry, nor Edit nor Cancel button react. Only way is to kill the report via Task Manager. 

Zipping the PBIX report and removing on the zipped folder the 'connection' folder does not resolve this issue. Any idea if is possible to recover the old report and to re-post it to the new data source?

Thank you in advance for your help.

Hi ,  @schaema3 

Have you tried to clear the original data source permission?

Try to open a new powerbi desktop, and clear the datasource permission.

After that, please reopen and  reconfigure  your  pbix file .

Hi Eason,

that doesn't work either. I tried both, opening a new report clearing the data source permissions, closing Power BI and re-opening the broken report and opening the report out of Power BI without closing the app. Both result in the same. Only way is killing the process with the task manager, no way to either get access or to even close the app.

Hey @schaema3 

You should be able to open the PBIX, Open Query Editor, click on the gear icon next to source in the applied steps pane to the right and change the source. It should attempt to refresh or reload when you do this. I do this regularly as I have to fix the source for everything from SQL tables to Excel files whenever they are renamed.

Is it freezing on you before this part of the process?

If this helps please kudo. 

If this solves your problem please accept it as a solution.

Hi Tad17,

Yes, it freezes before you actually can access the report to do modifications. I couldn't find any way to get on. Looks to me like a BI bug.
