Depending on your business needs, it may be necessary to edit the product prices. The changes that you make to the product prices are visible in the current reference catalog only after activation.
You have to activate the changes to make them visible in the current reference catalog. Refer to Scheduling activation.
To see a new revision of product definitions, a catalog needs to 'Synchronize' the catalog to the revision. Refer to Synchronizing with reference catalog.
Price changes to existing products and bundles are not synchronized up to a channel catalog and have to be explicitly managed. When managing prices for a catalog (both products and bundles) the reference price of the product or bundle is visible to the product manager (in parentheses) in the product management UI.
