In SP Designer, when using the "Set Field in Current Item" action, if the field you are setting is a Person type, there are several choices to "return" the data as. For example, if setting your Person field to the current item's Modified By or Created By, these are also Person fields but can be returned as one of the following:
- As String
- Display Name
- Email Address
- Login Name
- User ID Number
Is there any gotcha in choosing one of these to set a Person field as? Is there any choice that won't set the person correctly and resolve it to a SharePoint person type?
