• Click on the Settings menu and select Supplier Settings.
  

• Navigate to the My Suppliers tab and click on the name of the supplier you want to assign a Product Set to.
  

• Select the Facebook tab to enable product sets for a Facebook Dynamic Product Ad or Sponsored Product. Alternatively, select the Google tab to enable Product Groups for a Google Smart Shopping Ad. Click the dropdown arrow next to Products.
  

• Use the dropdown menu to choose which Product Sets you want to enable or disable for the Supplier.
  

• Finally, click the Save Changes button at the top of the page to save your changes.
