1. Goal

The function module {{P}}CINE_FEE_OLD in function group {{P}}FG_CINE calculates the price of a cinema ticket order. The code is legacy code. Refactor the function module in place. The behavior stays the same. The name and the public interface stay the same.

2. Open questions

None.

3. Context

• Function group {{P}}FG_CINE exists in package $TMP.
• The function module {{P}}CINE_FEE_OLD exists in this function group. It holds the legacy code.
• A ticket desk program calls {{P}}CINE_FEE_OLD for each ticket order. This call must not change.

4. Contract

• Object: the function module {{P}}CINE_FEE_OLD in function group {{P}}FG_CINE.
• Keep the name and the interface of the function module: the same parameter names, parameter kinds, parameter types and the same exception.
• Importing parameters: iv_show_type TYPE string, iv_seats TYPE i, iv_show_time TYPE t, iv_cust_type TYPE string.
• Exporting parameters: ev_total TYPE decfloat34, ev_discount TYPE decfloat34.
• Exception: invalid_input.

5. Business rules

The legacy source code of {{P}}CINE_FEE_OLD is the only source of the business rules. Read this source code. The one rule of this task: for every input the function module returns the same output values and the same exception as before the refactoring. Do not add, remove or change a rule.

6. Constraints

• Release target: SAP_BASIS 816.
• Coding standards: Clean ABAP. No ATC priority 1 or priority 2 finding. Keep every procedure and every method below 40 statements. Replace literal numbers with named constants. Use meaningful names.
• Out of scope: do not change the interface. Do not change the function group {{P}}FG_CINE.

7. Acceptance

• {{P}}CINE_FEE_OLD 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.
