Hi @sjoerd timo van vliet , I understand that you want to use Scalar Function: datetime_utc_to_local() in your Azure Monitor DCR.
Unfortunately, that function is not supported. See Supported KQL features for a complete list of supported features. Only the functions listed under DateTime and TimeSpan functions can be used for date/time transformation.
