While an invoice is in either the Draft or Pending status, Value items within the invoice can be deleted.
NOTE: To delete Value items from an invoice, you need Modify permissions to Case > Invoicing Tab.
To remove one of the Value items from the invoice, click the kebab menu within the grid and select the Delete option.
Confirm your intention on the Delete Item message.
NOTE: The Value item is not deleted, it is only removed from the invoice.
The item will be removed when the Delete button is clicked. The Totals and Summary sections of the invoice will refresh, minus that removed item.
NOTE: If the Value item from the Values view of the Value Tab is deleted, it will automatically be removed from the associated invoice.
