One or more verified and active Business Profiles in your business group linked to your Google Merchant Center account are missing corresponding inventory data.
Review the Business Profiles in your linked business group to determine if you can provide inventory data for these businesses. If so, please integrate that data into your local product inventory feed by assigning a unique store code in your Business Profiles and then referencing that store code in your inventory data within your Merchant Center account.
Note: To serve local inventory ads and free local product listings, make sure the codes in your inventory data match store codes in your Business Profiles.
