# 1. Goal
|
|
Calculate the discount percentage for a wholesale order. A sales program calls the
|
|
calculation before it prices the order. The program needs one discount percentage
|
|
for each order.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- The interface {{P}}IF_DISCOUNT exists in package $TMP. It is active.
|
|
- The interface has the type TY_GROUP (CHAR 1), the type TY_PERCENT (P length 5
|
|
with 2 decimals), the constants C_GROUP_KEY ('A') and C_GROUP_STANDARD ('S'),
|
|
and one method:
|
|
CALCULATE IMPORTING iv_quantity TYPE i
|
|
iv_group TYPE ty_group
|
|
RETURNING VALUE(rv_percent) TYPE ty_percent.
|
|
|
|
# 4. Contract
|
|
- Create the class {{P}}VOLUME_DISCOUNT in package $TMP.
|
|
- The class is public, final, and has a public constructor without parameters.
|
|
- The class implements {{P}}IF_DISCOUNT.
|
|
- Do not add other public methods.
|
|
|
|
# 5. Business rules
|
|
The discount percentage is the sum of the customer discount and the volume
|
|
discount. The result is at most 12.00.
|
|
1. Customer discount:
|
|
- Group C_GROUP_KEY: 6.00.
|
|
- Group C_GROUP_STANDARD: 0.00.
|
|
- Any other group: 0.00.
|
|
2. Volume discount. The order quantity is the number of pieces:
|
|
- Less than 100 pieces: 0.00.
|
|
- More than 100 pieces and less than 500 pieces: 3.00.
|
|
- 500 pieces or more: 7.00.
|
|
3. Add the customer discount and the volume discount. If the sum is more than
|
|
12.00, the result is 12.00.
|
|
|
|
# 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_DISCOUNT.
|
|
- If a business rule is missing or two business rules contradict, do not create
|
|
the object. Report the gap.
|
|
|
|
# 7. Acceptance
|
|
- The class is active and has no syntax error.
|
|
- Write your own ABAP Unit tests for the class.
