Switch products to work with items, requests, and baselines that are owned by a different product.
You can use a product that is different from the one that owns the current project/stream. If the current project/stream is set to $GENERIC:$GLOBAL, setting a product enables you to see an actual design part structure in the navigation pane.
To switch products:
In the status area at the bottom of the web client window, click the change button next to the product. The Change Product dialog box opens.
To change to a different product, select a product in the Product Name list.
To change to the product that owns your current project/stream, select <default> in the Product Name list. This will automatically switch to the product that owns the project/stream whenever you change project/streams.
