To add a fourth party vendor, start by navigating to Vendors under the Vendor Risk heading. Select the third party vendor that you know uses a particular (fourth party) vendor and select '+New Fourth Party'.
Next, search for the vendor which you know is associated with your third party and hit 'Select Vendor'.
From here you can either:
Add the fourth party vendor without an associated product, by selecting 'Save Fourth Party without products'
Select a pre-existing product
Add a new product
When you are done, hit 'Save Fourth Party' and you will see your updated list of fourth parties with your newly added vendor.
Adding a new product
Adding a new product is as simple as filling in the product name, selecting or creating a category and optionally adding a description.
