1. Goal

Refactor the legacy function module {{P}}MUSEUM_FEE_OLD in function group {{P}}FG_MUSEUM. The function module calculates the entry fee for a museum visit. The behavior of the function module must stay the same. Improve the code quality.

2. Open questions

None.

3. Context

• Function group {{P}}FG_MUSEUM exists in package $TMP.
• Function module {{P}}MUSEUM_FEE_OLD exists in this group. It contains legacy code.
• The function module is called by a ticketing program. The interface must not change.

4. Contract

• Refactor the function module {{P}}MUSEUM_FEE_OLD in function group {{P}}FG_MUSEUM.
• Keep the name and the public interface: the same parameter names, kinds, types, and exceptions.

5. Business rules

1. The behavior of the function module must not change. The legacy code defines the business rules.
2. The function module must raise the exception INVALID_INPUT for the same inputs as the legacy code.
3. The exported values must be the same as the legacy code for all valid inputs.

6. Constraints

• Release target: 8.16.
• Coding standards: Clean ABAP, no ATC priority 1 or 2 findings, methods below 40 statements.
• Out of scope: none.

7. Acceptance

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