The Pharmacy product search tab is the same search tab that is available under the Navigation window. The only difference is that the Back button will return to this tab.
The tab is composed of three parts: The Presc Search panel to look up products based on certain parameters or keywords, the Presc List that outputs the results, and the Product Details screen.
Product Details contains subtabs where you can customize the product pricing, associate generics, and build out interaction warnings.
