1. Goal

Calculate the fee of one driving lesson for a driving school. The lesson booking program calls one function module for each completed lesson. The function module must have the same interface as the sample lesson module, because the booking program calls all lesson modules in the same way.

2. Open questions

None.

3. Context

• Function group {{P}}FG_DRIVE exists in package $TMP.
• Function module {{P}}DRV_SAMPLE exists in this group. It is the sample lesson module. Its interface is the interface that all lesson modules must use.

4. Contract

• Create the function module {{P}}DRV_FEE in function group {{P}}FG_DRIVE.
• Use exactly the interface of {{P}}DRV_SAMPLE: the same parameter names, kinds and types, and the same exceptions.

5. Business rules

1. If iv_minutes is less than 1, raise the exception INVALID_MINUTES. This rule applies before all other rules.
2. The rate of one lesson minute depends on the vehicle: CAR 1.20, TRUCK 2.50, MOTORCYCLE 0.90.
3. If iv_vehicle is not one of these three values, the fee is 0 and the block flag is false. Do not raise an exception. This rule also applies when iv_minutes is more than 120.
4. The fee is the rate multiplied by iv_minutes.
5. The lesson type adds a surcharge to this amount: NIGHT 25 %, MOTORWAY 40 %. All other lesson types have no surcharge.
6. Round the fee half up to 2 decimals.
7. The minimum fee of one lesson is 15.00.
8. Set the block flag to true if iv_minutes is more than 120. Set the block flag to false in all other cases.

6. Constraints

• Release target: 7.40 SP05. Use only syntax that this release supports.
• Coding standards: Clean ABAP. No ATC priority 1 or priority 2 findings.
• Out of scope: do not change {{P}}DRV_SAMPLE.

7. Acceptance

• The function module is active and has no syntax error.
• The hidden tests pass.
• Write ABAP Unit tests for the function module in a global test class.
