# 1. Goal
|
|
Calculate the fee of a campsite pitch booking. The booking program calls one
|
|
function module for each booking. The function module must have the same
|
|
interface as the sample module {{P}}CAMP_SAMPLE, because the booking program
|
|
calls all fee modules in the same way.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- Function group {{P}}FG_CAMP exists in package $TMP.
|
|
- Function module {{P}}CAMP_SAMPLE exists in this group. It is the sample
|
|
module. Its interface is the interface that all campsite fee modules use.
|
|
- A booking has a pitch type, a number of nights, a number of adults, and an
|
|
electricity flag.
|
|
|
|
# 4. Contract
|
|
- Create the function module {{P}}CAMP_FEE in function group {{P}}FG_CAMP.
|
|
- Use exactly the interface of {{P}}CAMP_SAMPLE:
|
|
- Importing parameter iv_pitch_type, type string.
|
|
- Importing parameter iv_nights, type i.
|
|
- Importing parameter iv_adults, type i.
|
|
- Importing parameter iv_electricity, type abap_bool.
|
|
- Exporting parameter ev_discount, type abap_bool.
|
|
- Changing parameter cv_fee, type decfloat34.
|
|
- Exception invalid_nights.
|
|
|
|
# 5. Business rules
|
|
1. If iv_nights is less than 1, raise the exception INVALID_NIGHTS.
|
|
2. The nightly rate depends on the pitch type:
|
|
- STD: 12.00
|
|
- CMF: 18.00
|
|
- PRM: 25.00
|
|
- Any other pitch type is unknown.
|
|
3. If the pitch type is unknown, set cv_fee to 0.00, set ev_discount to false,
|
|
and stop. Do not apply rules 4 to 8.
|
|
4. Each adult adds 4.00 per night. If iv_adults is less than 1, count one
|
|
adult.
|
|
5. If iv_electricity is true, add 3.50 per night.
|
|
6. The subtotal is the sum of the nightly rate, the adult charge, and the
|
|
electricity charge, multiplied by the number of nights.
|
|
7. If iv_nights is 7 or more, reduce the subtotal by 15 % and set ev_discount
|
|
to true. Otherwise set ev_discount to false.
|
|
8. Round cv_fee half up to 2 decimals.
|
|
|
|
# 6. Constraints
|
|
- Release target: 7.40 SP05. Do not use ABAP syntax that is newer than this
|
|
release.
|
|
- Coding standards: Clean ABAP. Keep methods below 40 statements.
|
|
- Out of scope: do not change {{P}}CAMP_SAMPLE.
|
|
|
|
# 7. Acceptance
|
|
- The function module is active and has no syntax error.
|
|
- The hidden tests pass.
|
|
- Write ABAP Unit tests for the function module in a global test class.
