1. Goal
A freight forwarder calculates the price of an outbound shipment. The calculation service receives the gross weight, the volume, the transport distance, and the current fuel index. It returns the freight components and a reason code.
2. Open questions
None.
3. Context
- The interface {{P}}IF_FREIGHT_CALC exists in package $TMP. It is active.
- The interface defines the types TY_REASON, TY_AMOUNT, TY_WEIGHT, TY_VOLUME, TY_DISTANCE, TY_FUEL, and TY_RESULT.
- The interface defines the constant structure C_REASON with the components OK, WEIGHT, VOLUME, DISTANCE, and FUEL.
- The interface defines the instance method CALCULATE with the importing parameters IV_WEIGHT_KG, IV_VOLUME_M3, IV_DISTANCE_KM, IV_FUEL_INDEX and the returning parameter RS_RESULT.
4. Contract
- Create the class {{P}}FREIGHT_CALC in package $TMP.
- The class is public, final, and has a public constructor without parameters.
- The class implements {{P}}IF_FREIGHT_CALC.
- Do not add other public methods.
5. Business rules
All amounts are in euro. Apply the rules in this sequence.
- If IV_WEIGHT_KG is less than or equal to 0, return the reason WEIGHT. Set all amounts and the chargeable weight to 0.
- If IV_VOLUME_M3 is less than 0, return the reason VOLUME. Set all amounts and the chargeable weight to 0.
- If IV_DISTANCE_KM is less than or equal to 0, return the reason DISTANCE. Set all amounts and the chargeable weight to 0.
- If IV_FUEL_INDEX is less than 0 or greater than 100, return the reason FUEL. Set all amounts and the chargeable weight to 0.
- The volumetric weight is IV_VOLUME_M3 multiplied by 250.
- The chargeable weight is the greater of IV_WEIGHT_KG and the volumetric weight.
- The base freight is 45.00. For each full or partial 100 kg by which the chargeable weight is greater than 1000 kg, add 6.50.
- The distance freight is 0.00 for a distance up to and including 100 km. For each full or partial 100 km by which IV_DISTANCE_KM is greater than 100 km, add 9.00.
- The fuel freight is the sum of the base freight and the distance freight, multiplied by IV_FUEL_INDEX, divided by 100. Round the result to 2 decimal places. Round a half away from zero.
- The total is the sum of the base freight, the distance freight, and the fuel freight.
- Return the reason OK.
6. Constraints
- Release target: 7.40 SP05. Do not use syntax that is newer than 7.40 SP05. For example, do not use COND, SWITCH, REDUCE, FOR, or LET.
- 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_FREIGHT_CALC.
7. Acceptance
- The class is active and has no syntax error.
- The hidden tests pass.
- Write your own ABAP Unit tests for the class.
