Hello,
I'm using Power BI for a few months now. With a Pro account, I published and shared a report in a workspace. I use a gateway to refresh data automatically 8 times a day.
I hadn't any issue from the beggining, but since last week, the gateway can't refresh data, because of a "Memory error : Memory Allocation failure. Try simplifying or reducing the number of queries." The manual refresh doesn't work either.
I tried to refresh data from Power BI Desktop, but my PC had frozen during 2 hours, and after that, the same issue appeared : "The memory is insufficient to complete this operation".
I have a main table with 15 columns imported from my SQL Database, and 18 calculated columns (some LOOKUPVALUE, CALCULATE and FILTER functions) for 15'000 rows. It's joined to 4 others tables. Each of it has 2 columns for just a few rows. I don't think it's a lot of data.
I saw a lot of topics about this error, but I didn't see any solution to my case.
I can't remove any column, because I need all of it for my report.
My pbix file's size is 4 Mo and my group storage is 2 MB of 10 GB. In Options, my data cache is under 4 Mo.
I really don't understand why I have this error.
In Power BI Desktop, I added a query to keep only the last 10'000 rows for the refresh to limit the data's quantity, and the refresh (manual and automatic) work again . But I would like all my data for my analyzes.
Do you have an explanation for this memory's problem ?
Is there a limit of data, rows, calculation or something else for a report ?
