Audit log - missing value

[ninart]

Hi, 

I exported the Power BI audit log from the system and I found that there are some missing fields in the log. For example, there are some missing username  (blank field) in some rows while other field in the same row contain complete data. Does anyone have the same issue?  I want to know what factor can cause this to happen and how can I protect it? 

Cheers,

Hi , @ninart 

As far as I know, all user actions included in the search record of the Power BI Audit log are completed by the corresponding users in the tenant, so can you find an example to confirm whether this action is invited by users inside the organization or external users from the program outside the organization?

If convenient, you can also try using Power BI's ActivityEvents REST API to export data for the most recent day, and see if the corresponding user name field that appears empty in the search record of the Power BI Audit log shows a value.

For more information, you can refer to :

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
