Evaluation errors Dataflow

Hi,

Since yesterday a few of our dataflows encouter issues while trying to perform a refresh. I encountered the following error messages regarding evaluation of the datafow: 

 

Error: We're sorry an error occurred during evaluation.

Evaluation ran out of memory and can't continue.

 

In total 4 of our dataflows are not refreshing at the moment.

Is there anybody that encounters the same issue? Or any suggestions on how to fix it?

 

Thank you in advantage.

After having contact with Microsoft Support it seems there has been a general problem with dataflows in the Power BI service. After the weekend the issue was resolved.

We have the same problem AGAIN 🤔🤔🤔 !!!
I can't understand why Microsoft is so unstable on products they should get more attention!!!
It is these types of stresses that cause Technology Managers (TM) to do complex change decisions!!! 🙄🙄🙄

Hi @Jorenvdl ,

 

I think this may cause by the datasize is too large for dataflow to implement. Pleae connect admin to increase memory on the container for dataflows in your capacity or Increase memory to workload and more memory to container:

If not works, please consider a higher Power BI Premium SKU.

 

Please refer this article:

Configure Power BI Premium dataflow workloads - Power BI | Microsoft Docs

We have the same problem!!!
This is really happening in the last few days...
We believe that it is a problem in Power BI Service, because when using the same script (Power Query) in Power BI Desktop, the error does not occur and then the data loads successfully!! 🤔
