1. Goal

Refactor the legacy report {{P}}FLEET_COST_OLD in package $TMP. The report shows the running cost of each vehicle of a company fleet for a period. The behavior of the report stays the same. Improve the internal quality of the source code.

2. Open questions

None.

3. Context

• The program {{P}}FLEET_COST_OLD exists in package $TMP. It is active and it produces a correct result. Its source code is of poor quality.
• The tables {{P}}VEHICLE and {{P}}TRIP exist in package $TMP. They contain data. The report reads these two tables.
• The report shows the result in an ALV list.
• The users report no functional defect. Do not change the behavior.
• The report is not in the out-of-scope list. Refactor it in place.

4. Contract

• The program keeps the name {{P}}FLEET_COST_OLD and the package $TMP.
• The selection screen keeps these fields, in this order:
  • Parameter P_FROM, type DATS, mandatory.
  • Parameter P_TO, type DATS, mandatory.
  • Select-option S_CAT for the vehicle category.
• The ALV list keeps the same columns with the same names: VEHICLE_ID, PLATE, CATEGORY, DISTANCE, FUEL_COST, TOLL_COST, TOTAL_COST, COST_PER_KM.
• The lines of the list and the order of the lines do not change.

5. Business rules

The behavior stays the same. The legacy source code of {{P}}FLEET_COST_OLD contains all the rules. Read the legacy code. Keep every rule. Do not add a rule and do not remove a rule.

6. Constraints

• Release target: 8.16.
• Coding standards: Clean ABAP.
  • Do not read a database table inside a loop.
  • A method has less than 40 statements.
  • The maximum nesting depth is 3.
  • Use meaningful names.
• Out of scope: do not change the tables {{P}}VEHICLE and {{P}}TRIP. Do not change the selection screen fields. Do not change the ALV column names.

7. Acceptance

• The program {{P}}FLEET_COST_OLD is active and has no syntax error.
• The hidden tests pass.
• Write ABAP Unit tests as local test classes in the program.
