# 1. Goal
|
|
A tour operator wants a summary of the booking fees of one day. The booking
|
|
program calls one class for each day of the month and shows the summary.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- The interface {{P}}IF_TOUR_SUMMARY exists in package $TMP. It is active.
|
|
- The interface has the types TY_TOUR_TYPE, TY_STATUS, TY_BOOKING, TT_BOOKING
|
|
and TY_RESULT, the constant structure C_STATUS, and one method:
|
|
SUMMARIZE IMPORTING it_bookings TYPE tt_booking
|
|
RETURNING VALUE(rs_result) TYPE ty_result.
|
|
- The booking program passes the bookings of one day to the method.
|
|
- A day can have no bookings.
|
|
|
|
# 4. Contract
|
|
- Create the class {{P}}TOUR_SUMMARY in package $TMP.
|
|
- The class is public, final, and has a public constructor without parameters.
|
|
- The class implements {{P}}IF_TOUR_SUMMARY.
|
|
- Do not add other public methods.
|
|
|
|
# 5. Business rules
|
|
1. A tour type is 'C' (classic) or 'P' (premium).
|
|
2. If one booking has a negative number of adults or a negative number of
|
|
children, the summary is invalid. Return status 'N' and 0 in the fields
|
|
total_fee, booking_count and average_fee.
|
|
3. If one booking has a tour type that is not 'C' and not 'P', the summary is
|
|
invalid. Return status 'T' and 0 in the fields total_fee, booking_count and
|
|
average_fee.
|
|
4. Check rule 2 before rule 3.
|
|
5. The fee of one booking: an adult pays 20.00 for a classic tour and 30.00 for
|
|
a premium tour. A child pays half of the adult fee of the tour.
|
|
6. If the number of participants of one booking (adults plus children) is 10 or
|
|
more, reduce the fee of this booking by 10 percent.
|
|
7. Round the fee of each booking to 2 decimals. Round half up.
|
|
8. total_fee is the sum of the fees of all bookings.
|
|
9. booking_count is the number of bookings.
|
|
10. average_fee is total_fee divided by booking_count. Round half up to
|
|
2 decimals.
|
|
11. If the summary is valid, return status 'O'.
|
|
|
|
# 6. Constraints
|
|
