How come I don't see products in leads or opportunities?

You must enable and publish products and product groups in Adaptive Search before you see them in the leads and opportunities UIs. You can do this either using Setup Assistant or using this procedure.

1. In Setup and Maintenance go to: Sales offering > Sales Foundation functional area > Configure Adaptive Search task.
2. Click the Setup tab.
3. Select Product and Product Group and any other object you want to enable.
4. From the Actions menu, select Full Publish.
5. You can monitor the progress of the publish process on the Monitor tab.
