Power BI refresh failure

Hi anubhutani ,

Generally speaking, when the limit set by default is exceeded, some of the exceeded queries will fail and display "Partial query failed".

Your understanding is correct, you can change the size of the default limit by setting truncationmaxsize and truncationmaxrecords to solve the problem of error reporting.

Here is the reference document link: Query limits - Azure Data Explorer | Microsoft Docs
