1. Goal

Calculate the fee of hiring a marquee tent for an event. A booking program calls the calculation before it confirms a booking. The program needs the gross price in euro.

2. Open questions

None.

3. Context

  • Interface {{P}}IF_TENT_HIRE exists in package $TMP. It is active.
  • The interface has the type TY_AMOUNT (P LENGTH 15 DECIMALS 2), the constant structures C_RATE_S, C_RATE_M and C_RATE_L, the constants C_VAT, C_DISCOUNT and C_LONG_RENTAL_DAYS, and one method: CALCULATE_FEE IMPORTING iv_tent_size TYPE string iv_days TYPE i RETURNING VALUE(rv_fee) TYPE ty_amount.
  • Each rate structure has the components RATE_DAY and SETUP_FEE. C_RATE_S belongs to tent size S, C_RATE_M to tent size M and C_RATE_L to tent size L.
  • C_VAT is the value added tax rate. C_DISCOUNT is the discount rate. C_LONG_RENTAL_DAYS is the number of days from which the discount applies.

4. Contract

  • Create the class {{P}}TENT_HIRE_FEE in package $TMP.
  • The class is public, final, and has a public constructor without parameters.
  • The class implements {{P}}IF_TENT_HIRE.
  • Do not add other public methods.

5. Business rules

Apply the rules in this sequence.

  1. Read the daily rate and the setup fee for the tent size. Tent size S uses C_RATE_S, tent size M uses C_RATE_M and tent size L uses C_RATE_L. If the tent size is not S, M or L, return 0.
  2. The net price is the number of days multiplied by the daily rate plus the setup fee.
  3. If the number of days is C_LONG_RENTAL_DAYS or more, reduce the net price by C_DISCOUNT.
  4. Add value added tax of C_VAT to the net price. The result is the gross price in euro. The gross price must have two decimal places.

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}}IF_TENT_HIRE.

7. Acceptance

  • The class is active and has no syntax error.
  • Write your own ABAP Unit tests for the class.
