By default, all suppliers on a list that has supplier self reporting enabled will be required to report. To override this, you can exclude specific suppliers via their custom configuration.
From the main VendorPanel dashboard, navigate to the Enterprise Supplier Lists.
On the Manage Supplier List page, navigate to a list that has SSR enabled, then click on the button in the suppliers row to view suppliers on that list
Manage Supplier Lists - List with SSR enabled and button through to suppliers for that list
For the supplier you wish to set a customisation for, click on the right hand arrow and then click on the Self Reporting config link.
Manage supplier tooltip links with Self Reporting Config link
On this configuration screen you can disable reporting for this supplier.
Turn off reporting checkbox
This completely disabled self reporting for the supplier on the list. This setting takes precedence over all other SSR settings for this supplier. If disabled, the supplier loses all access to self reporting for this list, including access to previously submitted entries and will no longer be prompted to or reminded to complete reporting for this list.
