For an attribute to be recognized and stored for a product, it must first be defined in the type system (e.g., via an items.xml file). An Impex file can only populate attributes that already exist in the type system’s model. The other options are possible issues but are less directly related to an attribute simply not appearing.

Caching the results of expensive database operations, like product search and listing queries, is a fundamental and highly effective performance optimization in SAP Commerce. It prevents repeated database hits for the same data. While other options might offer marginal improvements, caching directly addresses the root cause identified: slow database queries.

The correct approach leverages SAP Commerce’s type system for clean, maintainable, and upgrade-safe extensibility. Adding a custom attribute ensures the data is properly modeled, persisted, and integrated into the platform’s services (like order history). Other options are workarounds that bypass the platform’s architecture, leading to fragile code and potential data loss.

SAP Commerce often uses a staged/production catalog version paradigm. Changes made in a staged version (like via PCM) must be published or synchronized to the online version that the storefront uses. This is the most common reason for such a discrepancy. Logs, roles, and browser cache are secondary checks if the version synchronization is confirmed correct.

A Content Delivery Network (CDN) is specifically designed to cache and serve static content from geographically distributed edge servers. This drastically reduces latency for end-users by serving assets from a location near them. The other options address different concerns: database clustering (data consistency), session replication (high availability for user sessions), and Solr configuration (search performance).

The promotion engine typically evaluates rules against specific cart subtotals (e.g., net total, delivery cost). If a custom module changes the order or logic of these calculations (e.g., calculating tax before promotions when it should be after), it can change the values the promotion engine sees, causing rules to not fire. The other options are less likely as they would cause complete failure, not incorrect logic.

OCC is the foundational REST API framework in SAP Commerce for headless commerce. It exposes commerce entities (carts, products, users, orders) and operations (add to cart, checkout) in a consumable way for decoupled front-end applications, enabling a true headless architecture.

Relevance ranking (scoring) in Solr is heavily influenced by boost factors. By applying a higher boost to matches in the `name` field compared to the `description` field, you directly influence the ranking to favor products where the search terms appear in the more important field. The other options affect search performance, index freshness, or query expansion, not specific field relevance.

This scenario can be modeled effectively using the out-of-the-box Promotion Engine. Conditions (Customer Group, Order Threshold) define when the rule fires. Promotion Groups and Exclusion rules are specifically designed to manage combinability (stacking) of promotions. This approach is configurable in Backoffice without deep code changes, aligning with best practices.
