+# 1. Goal
+A self-storage company rents storage units to private and business customers.
+The class {{P}}STORAGE_PRICER calculates the price of one storage unit
+booking. The class is legacy code. It works, but it is hard to read and hard
+to change. Refactor the class. The behavior stays exactly the same. The class
+name and the public interface stay the same.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The class {{P}}STORAGE_PRICER exists in package $TMP and is active.
+- A checkout program calls the method CALCULATE_PRICE for each booking.
+- The class is the only object of this task.
+
+# 4. Contract
+Keep the class {{P}}STORAGE_PRICER in package $TMP. Keep the class name and
+the public interface. The public interface is:
+- The class is public, final, and has a public constructor without parameters.
+- Public type TY_AMOUNT: packed number, length 8, 2 decimals.
+- Public type TY_SQM: integer.
+- Public type TY_MONTHS: integer.
+- Public type TY_BOOKING with the components SIZE_SQM (TYPE TY_SQM), MONTHS
+  (TYPE TY_MONTHS), CLIMATE (TYPE ABAP_BOOL) and INSURANCE (TYPE ABAP_BOOL).
+- Public method CALCULATE_PRICE with the importing parameter IS_BOOKING
+  (TYPE TY_BOOKING) and the returning parameter RV_PRICE (TYPE TY_AMOUNT).
+Do not add public methods or public components. Do not remove a public method
+or a public component.
+
+# 5. Business rules
+The legacy code in {{P}}STORAGE_PRICER contains all business rules. Read the
+legacy code. The behavior must stay exactly the same for every input. Do not
+add a rule and do not remove a rule.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP. Methods below 40 statements. No deep nesting.
+  No magic numbers; use constants. No global variables. No comment that
+  restates the code.
+- Out of scope: no other object.
+
+# 7. Acceptance
+- The class {{P}}STORAGE_PRICER is active and has no syntax error.
+- The public interface is unchanged.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
