More details:

• At least a sale price component "Ticket Price" must be created before creating a rate table
• When creating a rate table, a default "Ticket Price" price component must be selected, this ticket price component is used for all price breakdown within the same rate table.
• After rate table is created, a default price breakdown is created for the rate table.
• Operators start defining prices by entering a ticket price on "Amount" screen.
• Operators open the default price breakdown, select sale price components to continue the price calculation :
  • The "Mandatory sale price component": are selected by default and cannot be un-selected
  • When calculating price: Catalog price are also updated to total price of all price components - except the "Discount sale price component"
