In Salesforce, a product must have an active standard price defined before it can be added to any price book.
Without this, the product will not be available for selection within price books, which explains why the admin at Cloud Kicks is unable to add the new product.
* Activating Product for Price Books: By setting a standard active price, the product becomes eligible for inclusion in price books, allowing it to be sold and associated with opportunities.
* Ensuring Products are Ready for Sales: The standard active price acts as a baseline, ensuring that all products have a minimum price defined before they can be added to custom price books.
Option A (adding to a price schedule) is unrelated to price book eligibility, and Option B (editing sharing settings) pertains to access control, not price activation. For additional information, see Salesforce Product and Price Book Management.
