1. Goal

A ride-sharing service splits the cost of a shared ride between the passengers. The booking program calls the calculation after each completed ride. The program needs the total cost of the ride and the share of each passenger.

2. Open questions

None.

3. Context

• A ride has one driver and one or more passengers. The driver is not a passenger and pays nothing.
• The service charges a base fee, a distance fee and a detour fee.
• The booking program knows the distance of the ride in whole kilometres and the number of passengers of the ride.

4. Contract

• Create the class {{P}}RIDESHARE_SPLIT in package $TMP.
• The class is public and final. It has a public constructor without parameters.
• The class has these public types:
  • TY_DISTANCE: a whole number of kilometres.
  • TY_AMOUNT: a packed number with 2 decimals. The currency is euro.
• The class has these public methods. Do not add other public methods.
  • CALCULATE_TOTAL IMPORTING iv_distance_km TYPE ty_distance iv_passengers TYPE i RETURNING VALUE(rv_total) TYPE ty_amount
  • CALCULATE_SHARE IMPORTING iv_distance_km TYPE ty_distance iv_passengers TYPE i RETURNING VALUE(rv_share) TYPE ty_amount

5. Business rules

Apply the rules in this sequence.

1. The number of passengers is the number of persons who share the ride.
2. If the number of passengers is less than 1, the total cost is 0.00 and the share is 0.00. Rules 3 to 7 do not apply.
3. A distance below 0 counts as 0 kilometres.
4. The total cost of the ride is the sum of:
   • a base fee of 3.00,
   • a distance fee of 0.40 for each kilometre,
   • a detour fee of 1.20 for each passenger after the first passenger.
5. The share of a passenger is the total cost divided by the number of passengers.
6. Round the share to 2 decimals. Round a half away from zero (for example, 2.345 becomes 2.35).
7. The minimum share is 1.50. If the rounded share is below 1.50, the share is 1.50. The minimum share does not change the total cost.

6. Constraints

• Release target: 8.16 (SAP_BASIS 816).
• Coding standards: Clean ABAP. Methods below 40 statements. No global variables. No comment that restates the code.
• Out of scope: no database table, no CDS view, no report, no function module, no interface.

7. Acceptance

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