 # 1. Goal
-A customs broker calculates the import duty for a shipment. The broker program
-calls one function module for each shipment. The function module
-{{P}}CUSTOMS_DUTY_OLD calculates the duty rate and the duty. Users report
-several defects. Fix the function module in place. All other behavior stays the
-same.
+The function module {{P}}THEME_FEE calculates the price of a theme park ticket
+order. Users report three defects. Fix the defects in the function module. All
+other behavior stays the same.
 
 # 2. Open questions
 None.
 
 # 3. Context
-- Function group {{P}}FG_CUST exists in package $TMP.
-- Function module {{P}}CUSTOMS_DUTY_OLD exists in this group. It is the only
-  function module in the group. Read its source. It defines the duty rates of
-  the goods categories and all the other behavior that must stay the same.
-- The broker program calls the function module with a customs value, a country
-  of origin and a goods category. The program reads the duty rate and the duty.
+- Function group {{P}}FG_THEME exists in package $TMP.
+- Function module {{P}}THEME_FEE exists in this group. It is the function
+  module that the ticket program calls.
+- The function module has defects. Read the existing code before you change
+  it. The existing code holds rules that this specification does not repeat.
 
 # 4. Contract
-- Fix the function module {{P}}CUSTOMS_DUTY_OLD in function group {{P}}FG_CUST.
-- Do not change the interface. The parameters are:
-  - IV_VALUE, importing, decfloat34: the customs value in euro.
-  - IV_COUNTRY, importing, string: the country of origin.
-  - IV_CATEGORY, importing, string: the goods category.
-  - EV_RATE, exporting, decfloat34: the duty rate in percent.
-  - EV_DUTY, exporting, decfloat34: the duty in euro.
-  - The exception INVALID_VALUE stays.
+- Function module {{P}}THEME_FEE in function group {{P}}FG_THEME.
+- Parameters:
+  - iv_visitor_type TYPE string
+  - iv_tickets TYPE i
+  - iv_date TYPE d
+  - ev_unit_price TYPE decfloat34
+  - ev_total_price TYPE decfloat34
+  - ev_discount TYPE decfloat34
+- Exceptions: invalid_visitor_type, invalid_tickets.
+- Do not change the interface.
 
 # 5. Business rules
-1. The duty is rounded half up to 2 decimals. Users report duties with more
-   than 2 decimals, for example 6.185 instead of 6.19.
-2. The minimum duty is 5.00. The minimum applies only to a shipment that has a
-   duty. A shipment with a duty of zero keeps a duty of zero. Users report that
-   duty-free shipments are charged 5.00.
-3. A shipment with a preferential origin is duty-free: the duty is 0 and the
-   rate is 0. The preferential origins are Switzerland (CH), Germany (DE),
-   France (FR), Italy (IT) and Spain (ES). Users report that shipments from
-   France, Italy and Spain are charged duty.
-4. A negative customs value is not valid. Users report that a negative value is
-   accepted and gives a duty. The function module must raise the exception
-   INVALID_VALUE for a negative customs value.
-5. The duty rates of the goods categories and all other behavior stay the same
-   as they are in {{P}}CUSTOMS_DUTY_OLD today.
+The function module calculates the price of a theme park ticket order. These
+defects are reported:
+
+1. Peak season surcharge: The surcharge must apply only to visit dates in
+   June, July, or August. Currently the surcharge applies to all dates.
+2. Group discount: An order with 20 tickets or more must get a 15 % discount.
+   Currently an order with exactly 20 tickets gets only 10 %. An order with 10
+   to 19 tickets must get a 10 % discount. An order with fewer than 10 tickets
+   must get no discount.
+3. Rounding: The discount amount and the total price must be rounded to 2
+   decimals, half up. Currently they are not rounded. The discount amount is
+   rounded first. The total price is the gross amount minus the rounded
+   discount amount, rounded to 2 decimals.
+
+All other behavior stays the same.
 
 # 6. Constraints
-- Release target: 8.16 (SAP_BASIS 816, ABAP Platform 2025).
-- Package $TMP. Do not use transports.
-- Out of scope: do not change other objects.
-- Clean ABAP. Keep the methods below 40 statements.
+- Release target: SAP_BASIS 816.
+- Do not change the function module interface.
+- Out of scope: no other object.
 
 # 7. Acceptance
-- The function module {{P}}CUSTOMS_DUTY_OLD is active and has no syntax error.
+- The function module is active and has no syntax error.
 - The hidden tests pass.
 - Write ABAP Unit tests for the function module in a global test class.
