A supplier can be unpublished from the register by selecting the No option radio button in the Supplier Details form.

1. Go to Registers and select Suppliers
2. Find the supplier you want to un-approve and click on their title name
3. Select 'No' in the Supplier approved radio buttons

This will move the supplier to the "Not approved" tab. Only users with 'Approving Officer' permission levels or higher can access this feature.

Unapproved suppliers can be re-approved by selecting the Approve radio button option in the Supplier Details form.
