Memory Error while refreshing the dataset in Power BI Service

Hi neetu14 ,

" I have a premium capacity."

1. Check the size of the data set;

2. Check memory usage;

3. If both of the above conditions are positive, there may be a bug, please create support ticket .

Please refer to this link for specific content 

"Problem: Refresh is failing either with SQL Query Timeout or Memory Allocation Failure for the first time."

Try to update the gateway to the latest version:
