If a new Supplier has been added to your organization you can easily initialize it with the same Redemption configuration and capabilities like your existing Suppliers.
Here is how to do that
1. Navigate to the Supplier details, click Edit in the left
2. Toggle the Redemption Enabled flag, save your changes.
3. Go back to Edit (yes a little bit of a chicken-and-egg scenario)
4. In the left panel of the Edit screen at the top is a section with a button you can click to initialize the Redemption system for this Supplier.
Clicking that button will create a non-inventory, admin-only "wine" for this Supplier with the same Name and Code of each of your active Redemption Entries.
