Expression.Error: The evaluation reached the allowed cache entry size limit.

Hi All,

While import the data from Azure blob in Power BI, It shows the expression error 

Expression.Error: The evaluation reached the allowed cache entry size limit. Try increasing the allowed cache size.

Please suggest a solution to solve my issue.

This error shows up when a query in Power BI reaches the cache size limit. You can fix it by increasing the maximum cache size in settings under options and data load. If that doesn’t help, try simplifying the query by filtering data or splitting large steps.

Hi @Anonymous ,

Try to increase the Maximum allowed (MB).

Cache Size for Power BI Desktop

It's good practice that before you schedule the report, you validate the complete dataset. One additional help for this, especially in the cases of larger datasets retrieved from the API, is to increase the cache limits. This increase can improve PowerBI's performance and stability. To configure this:

1. Click Settings->Options->Global->Data Load to expose the "Data Cache Management Options".
2. Try increasing the Maximum allowed (MB):to 16000 (or about double what the current setting is).

The same thing happened to me, it turns out that the disk of the computer was almost full, when freeing memory it worked as before, be careful that Google Drive is not saving files on the computer, it may be the cause
