Preview target mappings (AD target systems)
For the relevant AD target system, Edit a target system.
Go to the Fields tab.
Click
Settings (next to the Preview button).
Select a person and account lifecycle stage to preview. Optionally, enable the Auto Run Preview toggle, which will cause previews to be updated any time you change a setting, without clicking the Preview button.
Click outside the popup to close it.
Target mappings for the given person and account lifecycle stage are displayed in the Preview Value column.

It is sometimes helpful to compare this preview to the original person object. To see the latter, View a person's data.
