Of course not! If your file has 10 columns and you only want SKU number and quantity on hand from the file you will want to use the attribute 'Ignore' for the other 8 attributes you do not want to map into ecomdash. The ignore value is used as a placeholder for the column.
1. Navigate to Settings > Inventory Settings > Import Format
2. Using the binoculars icon, click into the import format you created.
4. Under the Inventory Format Setup header, add "SKU Number" and "Quantity" in the correct column order that your file contains SKU and Quantity. For all the other attribute columns, use the "Ignore" attribute.
