A blank row in your "Sales by product" report may appear if there is missing or incomplete product data in your source, if a product title is not available for some sales records, or if an order includes only shipping, taxes, or fees (not tied to a specific product). This can happen when certain transactions lack a product title or if there are data sync issues.
How to troubleshoot the blank row:
Double-check your connected data sources and ensure all required connectors are active and syncing properly.
Break down by SKU/Product Title/etc, and the order lines that are not related to a product get represented as a null line.You can remove the empty line by adding a filter Product title is not null:
Create a custom dimension for you for the "product is null" filter so that you can see your gross sales without the shipping, discounts, order modifications added.
