Duplicate updates were suppressed

Duplicate updates were suppressed. This occurs when the same SKU appears multiple times in the same feed. Send only one update with the affected SKU to avoid seeing this warning.

This error might appear when the same Shopify product is added to two or even more Selling Lists in Salestio. When stock or price is updated for this product, Salestio sends the update from all Selling Lists where this product is added. As a result, this error appears. To resolve this error, make sure that no items appear in the Selling Lists twice.
