1. Goal

Calculate the monthly fee for a child at a day care centre. The billing program calls the calculation for each child before it creates the invoice. The program needs the fee and one reason code for each child.

2. Open questions

None.

3. Context

• The class {{P}}CHILDCARE_PRICER does not exist yet. Create it in package $TMP.
• The billing program is not part of this task. It calls the calculation for each child and reads the reason and the fee.

4. Contract

• Create the class {{P}}CHILDCARE_PRICER in package $TMP.
• The class is public, final, and has a public constructor without parameters.
• Define these public types: TY_AGE_BAND TYPE c LENGTH 4 TY_REASON TYPE c LENGTH 6 TY_AMOUNT TYPE p LENGTH 8 DECIMALS 2 TY_RESULT a structure with the components REASON (TY_REASON) and FEE (TY_AMOUNT)
• Define the public constant structure C_REASON with the components OK, AGE and DAYS. Each component has the type TY_REASON.
• Add one public method: CALCULATE IMPORTING iv_age_months TYPE i iv_days TYPE i iv_full_day TYPE abap_bool iv_sibling TYPE abap_bool RETURNING VALUE(rs_result) TYPE ty_result
• Do not add other public methods.

5. Business rules

Apply the rules in this sequence.

1. If iv_age_months is less than 3 or more than 60, return the reason AGE and the fee 0.
2. If iv_days is less than 1 or more than 5, return the reason DAYS and the fee 0.
3. Find the age band of the child: 3 to 11 months: BABY 12 to 35 months: TODD 36 to 60 months: PRE
4. Find the daily rate of the age band: BABY: 62.00 for a full day, 38.00 for a half day TODD: 54.00 for a full day, 33.00 for a half day PRE: 46.00 for a full day, 28.00 for a half day iv_full_day = abap_true means a full day. All other values mean a half day.
5. The monthly fee is the daily rate multiplied by iv_days and by 4.348. Round the result to 2 decimal places.
6. If iv_sibling = abap_true, multiply the monthly fee by 0.9 and round the result to 2 decimal places.
7. If the monthly fee is more than 1050.00, set it to 1050.00.
8. Return the reason OK and the monthly fee.

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: no other object.

7. Acceptance

• The class is active and has no syntax error.
• The hidden tests pass.
• Write your own ABAP Unit tests for the class.
