In WholeCell, Product Variations are a combination of:
conditions (damage conditions)
A SKU is an attribute of a Product Variation. You can assign the same SKU to multiple Product Variations if duplicate SKUs are enabled in your settings.
Adding New Product Variations
A new WholeCell account will have a default catalog of products, but will have zero Product Variations until you add inventory or upload a spreadsheet of product variations with "create" in the ID field of the Product Variations spreadsheet template:
SKUs can be edited in bulk via Product Variation spreadsheet upload or manually from a Product Variation's page.
WholeCell will not create in the catalog the entry in any row if the cells under the manufacturer, model, variant, network, capacity, color, and grade columns are blank. If you do not wish to add details for any of those product specifications, you must at least put "unknown" on the cells that you want to skip.
