# 1. Goal
|
|
Calculate the price of a booking at a recording studio. A booking program calls
|
|
the calculation before it shows the price to the customer. The program needs one
|
|
price for each booking.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- The interface {{P}}IF_STUDIO_PRICER exists in package $TMP. It is active.
|
|
- The interface has the type TY_ROOM (CHAR 1), the type TY_AMOUNT (packed, length
|
|
8, 2 decimals), the constant structure C_ROOM (A, B, C), and one method:
|
|
CALCULATE IMPORTING iv_room TYPE ty_room, iv_minutes TYPE i, iv_bookings TYPE i
|
|
RETURNING VALUE(rv_price) TYPE ty_amount.
|
|
|
|
# 4. Contract
|
|
- Create the class {{P}}STUDIO_PRICER in package $TMP.
|
|
- The class is public and final. It has a public constructor without parameters.
|
|
- The class implements {{P}}IF_STUDIO_PRICER.
|
|
- Do not add other public methods.
|
|
|
|
# 5. Business rules
|
|
Apply the rules in this sequence.
|
|
1. The room type is A, B, or C. Any other room type is invalid. For an invalid
|
|
room type, return 0.00.
|
|
2. The hourly rate depends on the room type: A 48.00, B 36.00, C 27.00.
|
|
3. The booking duration is given in minutes. A started hour counts as a full
|
|
hour. A booking of less than 60 minutes counts as one hour.
|
|
4. The base price is the hourly rate multiplied by the number of hours.
|
|
5. The loyalty discount is 0.75 percent for each booking of the customer in the
|
|
last 12 months. The discount is at most 15 percent.
|
|
6. The discount percentage is rounded.
|
|
7. The price is the base price minus the discount. The discount is the rounded
|
|
discount percentage of the base price.
|
|
8. Return the price.
|
|
|
|
# 6. Constraints
|
|
- Release target: 8.16.
|
|
- Coding standards: Clean ABAP. Method length below 40 statements. No global
|
|
variables. No comment that restates the code.
|
|

|
|
|
|
# 7. Acceptance
