+# 1. Goal
+A canal boat hire company prices the hire of a narrowboat. The booking program
+calls the calculation before it creates a booking confirmation. The calculation
+returns the hire price in euro and a reason code. A valid request returns the
+reason OK.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The class {{P}}HIRE_RATES exists in package $TMP. It is active and public.
+- The class provides the daily rate of each boat category and the season factor
+  of each month. Read the class in the system to learn its interface, the
+  category names and the rates. Do not change the class.
+
+# 4. Contract
+- Create the class {{P}}BOAT_HIRE_PRICER in package $TMP.
+- The class is public, final, and has a public constructor without parameters.
+- Public types:
+  - TY_REASON, type c, length 10.
+  - TY_PRICE, type p, length 10, 2 decimals.
+  - TY_RESULT, a structure with the components PRICE (type TY_PRICE) and
+    REASON (type TY_REASON).
+- Public constant structure C_REASON with the components OK, CATEGORY, DAYS,
+  CREW and MONTH. Each component has the type TY_REASON. The values are 'OK',
+  'CATEGORY', 'DAYS', 'CREW' and 'MONTH'.
+- One public method:
+  PRICE
+    IMPORTING iv_category      TYPE string
+              iv_days          TYPE i
+              iv_crew          TYPE i
+              iv_month         TYPE i
+    RETURNING VALUE(rs_result) TYPE ty_result.
+- Do not add other public methods.
+
+# 5. Business rules
+Apply the rules in this sequence. The first rule that fails decides the reason.
+If a rule fails, the result has this reason and the price 0.
+1. The category must be a category that {{P}}HIRE_RATES knows. The category
+   name is not case-sensitive. If not, return CATEGORY.
+2. iv_days must be between 1 and 28. If not, return DAYS.
+3. iv_crew must be between 1 and 12. If not, return CREW.
+4. iv_month must be between 1 and 12. If not, return MONTH.
+5. Calculate the base price: the daily rate of the category multiplied by
+   iv_days multiplied by the season factor of iv_month.
+6. If iv_days is 7 or more, subtract 10 % from the base price.
+7. If iv_crew is more than 6, add 15.00 EUR for each crew member above 6 for
+   each day of the hire.
+8. Round the result of rule 7 to 2 decimals. Return OK.
+
+# 6. Constraints
+- Release target: 8.16.
+- 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}}HIRE_RATES.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
