Managing Mass Update of Product Fields
Mass update allows you to bulk update fields, such as quantity, adjustment type, and adjustment amount for multiple products at a time. You can mass update standalone, bundle, and option line items on the Cart page. You can manually select line items to mass update or select them using Advanced Filter on the Cart page. Refer to Applying Advanced Filters on the Cart. However, CPQ does not apply mass updates to rollup line items even if you select them.
