We just released the January 2021 release of PBIRS that fixes several issues related to enhanced metadata models, please install the latest and let us know if that doesn't resolve your issue. Thanks!

Hi @sdhzhsz ,

Option 1:

In PBI Desktop Oct 2020, open every report query and data source

Change the connection information to all lowercase

Save the report and republish to PBIRS

Option 2:

Before the PBIX file is upgraded to the new format in the October 2020 version of PBI Desktop (Optimized for PBIRS), a backup copy is saved in the AppData folder:

C:\Users\<user>\AppData\Local\Microsoft\Power BI Desktop SSRS\TempSaves\Backups

Open PBI Desktop and turn off the Enhanced Metadata option. Go to File -> Options and settings -> Options -> Global-Preview features -> then uncheck the option:

Restart Power BI Desktop

Reopen the backup PBIX file

You should be able to use this version of the report and publish it to the PBIRS server. It is the v1 model and the same format as in May 2020 PBIRS.

If this post helps, then please consider Accept it as the solution to help the other members find it more quickly.

Best Regards,

I changed the datasource and it still doesn't work. The file in the backup folder is not the latest version , and I have made several updates. May I ask when you can launch an update to fix this problem, eagerly looking forward to

thank you very much

Have you checked Users' credentials under Datasource Tab on of report publish on PBIRS?

Is refresh working fine from Power BI Desktop optimized for Report Server?

[sdhzhsz]

Yes, It's OK.

It can also be successfully refreshed in power bi desktop.

by the way
