+# 1. Goal
+Calculate the toll that a vehicle pays for one journey on a toll road. A billing
+program calls the calculation for each journey. The program needs the toll in
+cents and one reason code for each journey.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The interface {{P}}IF_TOLL_PRICER exists in package $TMP. It is active.
+- The interface contains the type TY_JOURNEY for the input, the type TY_RESULT
+  for the output, the constant structure C_CLASS with the vehicle classes, the
+  constant structure C_REASON with the reason codes, and one method:
+  PRICE_JOURNEY IMPORTING is_journey TYPE ty_journey
+                RETURNING VALUE(rs_result) TYPE ty_result.
+
+# 4. Contract
+- Create the class {{P}}TOLL_PRICER in package $TMP.
+- The class is public, final and has a public constructor without parameters.
+- The class implements {{P}}IF_TOLL_PRICER.
+- Do not add other public methods.
+
+# 5. Business rules
+Apply the rules in this sequence. All amounts are in cents. Use integer
+arithmetic and discard remainders.
+1. Convert the vehicle class to upper case. The valid classes are M
+   (motorcycle), C (car), V (van) and L (lorry). If the class is not valid,
+   return the reason VEHICLE and the amount 0.
+2. The distance must be 1 kilometre or more and 130 kilometres or less. If not,
+   return the reason DISTANCE and the amount 0.
+3. The rate for each kilometre is 5 cents for M, 10 cents for C, 18 cents for V
+   and 30 cents for L. The toll is the distance multiplied by the rate.
+4. If the toll is below 100 cents, set the toll to 100 cents.
+5. If the vehicle has a transponder, subtract one tenth of the toll from the
+   toll. Example: a toll of 1000 cents becomes 900 cents.
+6. If the journey is at night and the vehicle class is L, add one quarter of the
+   toll to the toll. Example: a toll of 3000 cents becomes 3750 cents.
+7. Return the reason OK and the toll in the component amount_cents.
+
+# 6. Constraints
+- Release target: 8.16 (SAP_BASIS 816).
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change {{P}}IF_TOLL_PRICER.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
