The SKUs admin page controls which data is managed per SKU (per size) rather than per article. Both settings work the same way — when a setting is on, that value can be set per SKU and shows in the article flyout; when it's off, it isn't managed per SKU and doesn't show in the flyout at all.
The settings
Two things can be managed per SKU:
Price
Weight
For each one: on means it's set per SKU and the data appears in the article flyout; off means it's not shown in the flyout at all as all the SKUs share the same value. See Manage articles on a product for where this appears on the article and its SKUs.
💡 Turning a setting off doesn't delete anything — any values already entered per SKU are kept and reappear if you turn it back on.
SKUs with differing prices
With SKU-level pricing off, every SKU of an article should carry the same price. When some don't — typically prices set per size before the setting was turned off — the page lists them under SKUs with differing prices: one card per article, grouped by season, destination and supplier, with the differing values highlighted per size. Set all to this on a size copies its prices onto the other sizes and recalculates; Rescan refreshes the list, and Recalculate calculated fields runs a background job that re-derives the linked and calculated prices on every listed article. The section only appears while SKU-level pricing is off.
