Keep your storefront running smoothly even when your external inventory and Salesforce product catalog aren't in sync. The Eligible Promotions and the Promotion Evaluation and Execution APIs no longer reject items that aren’t yet synced to the Salesforce catalog. Instead, the APIs ignore the unsynced products in a cart and apply line-level and cross-line level promotions only to the synced items.
Where: This change applies to Lightning Experience in Enterprise, Performance, Unlimited, and Developer editions with Loyalty Management.
