# 1. Goal
A bicycle repair shop prices repair jobs. The workshop program calls one function
module for each repair job before it prints the work order. The new function
module must have the same interface as the sample pricing module, because the
workshop program calls all pricing modules in the same way.

# 2. Open questions
None.

# 3. Context
- Function group {{P}}FG_REPAIR exists in package $TMP.
- Function module {{P}}REPAIR_SAMPLE exists in this group. It is the sample
  pricing module. Its interface is the interface that all pricing modules must
  use.

# 4. Contract
- Create the function module {{P}}REPAIR_FEE in function group {{P}}FG_REPAIR.
- Use exactly the interface of {{P}}REPAIR_SAMPLE: the same parameter names,
  kinds, types, and exceptions.

# 5. Business rules
1. If the hours are less than zero, raise the exception INVALID_HOURS.
2. The hourly rate depends on the repair type:
   - 'BR' brake repair: 60.00
   - 'GE' gear repair: 45.00
   - 'WH' wheel repair: 30.00
   - every other type: 40.00
3. The labour fee is the hours multiplied by the hourly rate. Round the labour
   fee half up to 2 decimals. Return it in ev_labour_fee.
4. If the customer is a club member, reduce the labour fee by 10 %. Round the
   reduction half up to 2 decimals. Return the reduced labour fee in
   ev_labour_fee.
5. The total fee is the labour fee from rule 3 or rule 4 plus the parts cost.
   Return it in ev_total_fee.
6. If the total fee is less than 25.00, set the total fee to 25.00.

# 6. Constraints
- Release target: 7.02. Use only syntax that release 7.02 supports.
- Coding standards: Clean ABAP. Keep every method below 40 statements.
- Out of scope: do not change {{P}}REPAIR_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.
