What happens to the current product dimension when new products are imported?

When new products are imported into the product dimension, the process typically involves merging these new members into the existing product dimension, meaning they coexist alongside the existing entries without deleting or clearing them. This combination preserves the historical context of the existing data while allowing the inclusion of newer items.

Merging the new members means that they are integrated directly into the dimension rather than being placed at the bottom or replacing the existing products altogether. The dimension itself is updated to reflect the latest products while all the previous data remains intact.

This integration method is essential for maintaining data integrity and historical relationships between existing products and any new additions, ensuring continuity in reporting and analysis. Thus, the correct response reflects the method used for product dimension updates in a data import scenario.
