# 1. Goal
|
|
An auction house charges a buyer's premium on each lot that it sells. The
|
|
auction program calls one premium module for each sold lot. The premium module
|
|
must use the same interface as the sample module {{P}}AUC_SAMPLE, because the
|
|
auction program calls all premium modules in the same way.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- Function group {{P}}FG_AUCT exists in package $TMP.
|
|
- Function module {{P}}AUC_SAMPLE exists in this group. It is the sample
|
|
premium module. Its interface is the interface that all premium modules must
|
|
use.
|
|
|
|
# 4. Contract
|
|
- Create the function module {{P}}AUC_PREMIUM in function group {{P}}FG_AUCT.
|
|
- Use exactly the interface of {{P}}AUC_SAMPLE: the same parameter names, kinds,
|
|
types, and exceptions.
|
|
- The exception is INVALID_HAMMER.
|
|
|
|
# 5. Business rules
|
|
1. If the hammer price is less than 0, raise the exception INVALID_HAMMER and
|
|
stop.
|
|
2. Set the skip flag to false, except in rule 3.
|
|
3. Lot type C (charity): set the skip flag to true. Leave the fee unchanged and
|
|
stop.
|
|
4. For every other lot type, calculate the band premium from the hammer price:
|
|
- the part of the hammer price up to 1,000.00: 20 %
|
|
- the part of the hammer price above 1,000.00 up to 10,000.00: 12 %
|
|
- the part of the hammer price above 10,000.00: 6 %
|
|
5. Channel O (online): the premium is 90 % of the band premium. For every other
|
|
channel the premium is the band premium.
|
|
6. Round the premium of rule 5 half up to 2 decimals.
|
|
7. The minimum premium is 5.00. The maximum premium is 5,000.00.
|
|
8. The fee is the premium of rules 4 to 7.
|
|
|
|
# 6. Constraints
|
|
- Release target: 7.02. The code must run on a 7.02 system. Do not use syntax
|
|
that was introduced after release 7.02.
|
|
- Coding standards: Clean ABAP.
|
|
- Out of scope: do not change {{P}}AUC_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.
