Semantic –"An error occurred in Power BI Prem/"The Database exceeds the maximum size limit on disk"

[Veronika_Just]

Hi, 
I had been working on a dataset online and next day actualization failed and the first error ocured.

"There was an error when processing the data in the dataset."

I've been in touch with Microsoft support since that day. In my team, we all have Pro version.

I've tried
publishing previous version,
my collegues have tried,
we checked size of data comming from database into the cloud and cut the most of it,
cut of most of the data in database in desktop,
deleted parametric tables and columns,
checked the size of the workspace, 
... everything I've found on internet. 
I have no problem publishing it into this workspace under different name or elsewere and refresh it.
Microsoft support wasn't able help me, one screening session and numerous emails later I'm here.

Today I've tried upload the last succesfully re-published version - from 02_2025 and I got new error message. 

"An error occurred in Power BI Premium backend services."

I'm really desperate, there are five reports directly connected to this model, all of them I'm not able to open, edit, or even dowland. I can't lose them, there is no backup, and I have no idea what three of them even look like.

Please, has anyone ever summoned something like this?

Hi @Veronika_Just 

Thank you for reaching out microsoft fabric community forum.Since you're using Power BI Pro, your workspace is likely on shared capacity, which has limited resources and no detailed metrics. That could explain the refresh failures if the dataset uses too much memory during processing.

To confirm:

• Go to the workspace in Power BI online.
• Click the gear icon (⚙️) > Workspace settings.
• Under the Premium/Capacity tab, check if Premium is turned on or off.

  If it’s off, you’re on shared capacity. Even if the .pbix file size seems fine, refresh errors can still happen if the model is too complex or heavy for the shared environment.

  You can try:

  • Publishing to a Fabric trial workspace (if available).

  • Testing in a Premium Per User (PPU) environment.

  • Using Performance Analyzer in Power BI Desktop to optimize queries.

Hi, thank you for your reply!

We have only Pro version. Is there a way I can see somewhere what our capacity SKU is?
All capacity - workspace/size of .pbix looks okay, I could ask Premium for our project but I need some proof we are out of some capacity.

Your Premium SKU is too small?  Not much you can do about that now as you cannot update to a larger P SKU. You will have to start thinking about migrating to F SKUs.
