Common source patterns
- InfoPath Contact Selector or people picker.
- A User Roles list where dropdowns display Name and save Email.
- Text fields that store display names only.
- Hidden fields that store account IDs, emails, or claims-like values.
Flatten or preserve identity
Flatten to text/email when the app only needs to display or notify a person. Use SharePoint Person columns when the app needs directory-aware people selection, profile cards, or person-column filtering.
Test cases
- Select a user in the generated app.
- Submit the item.
- Confirm SharePoint stores the expected value type.
- Open the record again and confirm the selected person displays correctly.
- Test with a different user account if permissions or claims formatting may differ.
