# 1. Goal
|
|
A scaffolding company hires out scaffold parts to building sites. A quotation
|
|
program calls the fee calculation for each hire order before it prints the
|
|
quotation. The program needs the final fee and the long-hire discount of the
|
|
hire order.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- The interface {{P}}IF_HIRE_FEE exists in package $TMP. It is active.
|
|
- The interface has the type TY_AMOUNT (packed, length 8, 2 decimals) and the
|
|
structure type TY_RESULT with the components FEE and DISCOUNT. Both
|
|
components have the type TY_AMOUNT.
|
|
- The interface has one method:
|
|
CALCULATE_FEE
|
|
IMPORTING iv_days TYPE i
|
|
iv_parts TYPE i
|
|
iv_express TYPE abap_bool
|
|
RETURNING VALUE(rs_result) TYPE ty_result.
|
|
|
|
# 4. Contract
|
|
- Create the class {{P}}SCAFFOLD_FEE in package $TMP.
|
|
- The class is public, final, and has a public constructor without parameters.
|
|
- The class implements {{P}}IF_HIRE_FEE.
|
|
- Do not add other public methods.
|
|
|
|
# 5. Business rules
|
|
1. The daily rate of one scaffold part is 4.20 EUR.
|
|
2. The base fee is IV_DAYS multiplied by IV_PARTS multiplied by the daily rate.
|
|
3. If IV_EXPRESS is true, the express surcharge is 12 percent of the base fee.
|
|
Round the express surcharge up to the next full cent.
|
|
4. If IV_DAYS is greater than 30, the long-hire discount is 6 percent of the
|
|
base fee.
|
|
5. The final fee is the base fee plus the express surcharge minus the long-hire
|
|
discount.
|
|
6. The result contains the final fee in the component FEE and the long-hire
|
|
discount in the component DISCOUNT.
|
|
7. The final fee and the discount are amounts in EUR. Each amount is exact to
|
|
the cent.
|
|
8. If IV_DAYS is not greater than 30, the discount is zero.
|
|
|
|
# 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_HIRE_FEE.
|
|
|
|
# 7. Acceptance
|
|
- The class is active and has no syntax error.
|
|
- Write your own ABAP Unit tests for the class.
