PowerApps Canvas App - How to populate a People picker with value selected from Combobox

Question

I have a PowerApps Canvas app connected to a SharePoint Library, and I am trying to work around the Lookup/People field threshold from SharePoint. So I added the Office 365 Users connector, and a ComboBox (formatted as a Person field). I have a few of these, and basically I want various Approvers to have the option to Reassign to someone. I have a "Reassigned To" people picker from SharePoint that I want to populate with the user selected in the ComboBox. I tried this formula in the Reassigned To people picker's Defaulsselecteditems: {Value: ComboBox1.Selected.DisplayName} . This populates correctly in the form, but doesn't write to SharePoint. How can I accomplish this?

Thank you!

The people field in SharePoint has a different structure than a Choice field. To populate the default of a People field, you need to provide the core elements of the People object, which is DisplayName, Claims and Email. You should be able to get these from your selected item in the combobox.

Here is an example of how I populate the current user into a people field. You can use this as a guide and change the User().FullName etc with the respective values of the ComboBox1.Selected.

This goes into the DefaultSelectedItems property of the control.

{ 
  DisplayName:User().FullName,
  Claims:"i:0#.f|membership|" & Lower(User().Email), 
  Department:"",  
  Email:User().Email, 
  JobTitle:"", 
  Picture:""
}

Using Combobox1, you might need:

{ 
  DisplayName:ComboBox1.Selected.DisplayName,
  Claims:ComboBox1.Selected.Claims, 
  Department:"",  
  Email:ComboBox1.Selected.Email, 
  JobTitle:"", 
  Picture:""
}
