You can add charge types to a product based on your business requirements.
Go to ADMIN SETUP > Pricing Administration > Price Lists.
The Price Lists page is displayed.
Click the required price list name link to open the Price Lists details page.
Click the Price List Items tab.
Search for the product to which you want to add a charge type.
Click the ellipsis icon next to a product name and click Add Charge Type. A new charge type is added for the selected product. Multiple charge types for the same price list are together.
Charge types save automatically when added, without requiring the SAVE button. This ensures updates are reflected immediately and prevents incorrect messages when deleted without saving.
