Symptoms
After generating a Google Base feed, the feed file does not contain any products, even though valid products exist that should be included.
Cause
The products are not mapped to a store.
NOTE: This pertains to ML9 versions SP1+ and MultiStore 9.1.0.0+
Solution
Map the products to stores and regenerate the feed.
If the storefront is for a single license store, you can map all products to the store using a SQL query.
NOTE: Before running the query, backup the database! This procedure should only be performed by knowledgeable database managers.
INSERT INTO ProductStore (ProductID)
SELECT ProductID
FROM Product
