Explanation:

In Salesforce Industries CPQ (Vlocity Cart), once a line item is added and configured, you do not need to remove and re-add it to change its configuration. Instead, you can use the Cart Line Item Actions menu to directly modify the product.

✅ How to change configuration:
Click the Actions menu next to the line item in the Cart.
Select Configure to reopen the configuration UI.
You can then update attributes, pricing options, or bundled components as needed.

This approach supports:
Mid-cycle changes without disrupting the Cart structure.
MACD flows (Move, Add, Change, Disconnect) for existing assets.
Efficient updates during quoting or ordering without reinitializing the product.
