There are three types of personal information which any user can update via Self service. 

To update personal details, using the left hand menu go to:

Self service > My details

Here, you can change the following:

1. Personal details
2. Bank Details
3. Emergency Contact Details. 

You can also access these pages via the 'What would you like to do?' option on the homepage

If you wish to amend what fields are changeable on the 'Personal details' page then go to:

Administration > Company > Settings > Company settings

Then go to the 'Self service' section.

Please note: Whilst updating this information does not require approval, these updates will generate a notification to your HR department or Line Manager (dependent on how your Natural HR system is set up), notifying them of the change.
