1. Goal

Calculate the hire fee of a mobile crane job. A quotation program calls the calculation before it sends a quote to the customer. The program needs the fee and one reason code for each request.

2. Open questions

None.

3. Context

• Interface {{P}}IF_CRANE_HIRE exists in package $TMP. It is active.
• Read the interface. It contains the types, the reason codes and the signature of the calculation method. Use the names of the interface.
• The method receives the working radius, the load, the ground type and a flag for a road permit. It returns a reason code and a fee.

4. Contract

• Create the class {{P}}CRANE_HIRE_CALC in package $TMP.
• The class is public and final. It has a public constructor without parameters.
• The class implements {{P}}IF_CRANE_HIRE.
• Do not add other public methods.

5. Business rules

Apply the rules in this sequence.

1. If the radius is less than 5 or more than 60, return the radius reason and a fee of 0.
2. If the load is less than 500, return the load reason and a fee of 0.
3. The crane has a load chart. The maximum load depends on the radius: radius up to 10 m: 12000 kg, up to 20 m: 8000 kg, up to 30 m: 5000 kg, up to 45 m: 3000 kg, up to 60 m: 1500 kg. If the load is more than the maximum load for the radius, return the capacity reason and a fee of 0.
4. Remove the leading and the trailing spaces from the ground type. Convert it to upper case. The ground type must be ROAD, GRAVEL or SOIL. If not, return the ground reason and a fee of 0.
5. Calculate the base fee: the radius in metres multiplied by 15, plus the load in kilograms divided by 100 and rounded down, multiplied by 5.
6. Multiply the base fee by the ground factor and divide the result by 100. The ground factors are: ROAD 100, GRAVEL 115, SOIL 135.
7. If the road permit is required, add 250 to the fee.
8. If the fee is less than 300, set the fee to 300.
9. Return the OK reason and the fee. Round each multiplication by a ground factor to the nearest whole euro. Round halves up. The fee is a whole number of euros.

6. Constraints

• Release target: ABAP Platform 2025 (SAP_BASIS 816).
• 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_CRANE_HIRE.

7. Acceptance

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