- Device & OS
- not provided
- Scenario
- Submitting records anonymously through a Power Apps portal into Dataverse.
- Observed behavior
- The creator of the Dataverse record is recorded as a Microsoft-managed Portals user or portal application user rather than SYSTEM.
Gather your specific portal configuration, table permissions, the exact creation date of the affected records, and the name of the displayed creator account to prepare for troubleshooting.
Consult the Official Power Apps Community
Because this issue involves Microsoft portal infrastructure and internal security behavior, getting specialized help from the official community is the recommended approach.
Changes to Microsoft's portal infrastructure or security behaviors can shift how anonymous submissions are logged. Instead of defaulting to SYSTEM, the environment may assign the action to a Microsoft-managed portal application user for better auditing and security tracking.
Since this is a backend behavior of Microsoft Dataverse and Power Apps, direct configuration fixes may require Microsoft support or advanced community insights.
Document your portal configuration, table permissions, the exact creation date of the records, and the displayed creator account name in Dataverse.
Visit the official Power Apps Community at https://powerusers.microsoft.com/t5/Power-Apps-Community/ct-p/PowerApps1.
Create a new topic detailing your anonymous portal user setup and the unexpected 'Created By' behavior to receive specialized guidance from Dataverse experts.

Frequently Asked Questions
Why do anonymous Power Apps portal submissions no longer show as SYSTEM?
Microsoft periodically updates portal infrastructure and security protocols. These updates often cause anonymous portal interactions to be logged under a designated portal application user rather than the generic SYSTEM account to improve auditing and track exactly which portal service created the record.
Can I manually change the 'Created By' field for portal records?
The 'Created By' field is a system-managed field in Dataverse and typically cannot be directly modified by users during standard data entry. Any modifications to this attribution would generally require advanced administrative privileges, plugins, or specific API configurations.
Where can I find my current table permissions for Power Apps portals?
You can review and configure your portal's table permissions within the Power Pages management app or the Portal Management app. Navigate to the 'Security' section and select 'Table Permissions' to review the access levels granted to anonymous and authenticated web roles.
