1. Goal

A wind farm operator needs the revenue of each wind turbine. The revenue is the yield of the turbine multiplied by the feed-in tariff of the wind park of the turbine. A report and an OData service read the revenue, so the calculation must be in the database, in a CDS view.

2. Open questions

None.

3. Context

• Table {{P}}WPARK (wind park), package $TMP. Key: PARK_ID (CHAR 10). Fields: PARK_NAME (CHAR 40), COUNTRY (CHAR 3), TARIFF (DEC 15,2). TARIFF is the feed-in tariff in euro for one MWh.
• Table {{P}}TURBINE (wind turbine), package $TMP. Key: TURBINE_ID (CHAR 10). Fields: PARK_ID (CHAR 10), NOMINAL_KW (INT4), YIELD_MWH (DEC 15,2). YIELD_MWH is the yield of the turbine in MWh.

4. Contract

• Create the CDS view entity {{P}}I_TURBINE in package $TMP.
• Elements, with these names: TURBINE_ID (key), PARK_ID, NOMINAL_KW, YIELD_MWH, REVENUE.
• The view exposes an association with the name _PARK. The target of _PARK is the wind park of the turbine.
• A caller reads the data of the wind park from the view with a path expression, for example _PARK-PARK_NAME or _PARK-COUNTRY.
• No authorization check (#NOT_REQUIRED).

5. Business rules

1. The view shows one row for each turbine in {{P}}TURBINE.
2. PARK_ID is the park of the turbine.
3. NOMINAL_KW is the nominal power of the turbine.
4. YIELD_MWH is the yield of the turbine.
5. REVENUE is YIELD_MWH multiplied by the TARIFF of the wind park of the turbine. REVENUE has 2 decimals.
6. _PARK points to the row of {{P}}WPARK that has the same PARK_ID as the turbine.
7. PARK_NAME, COUNTRY and TARIFF of the wind park are available through _PARK.

6. Constraints

• Release target: 8.16.
• Coding standards: Clean ABAP.
• Out of scope: do not change {{P}}WPARK and {{P}}TURBINE.

7. Acceptance

• The view is active and has no syntax error.
• The hidden tests pass.
• Write ABAP Unit tests with CL_CDS_TEST_ENVIRONMENT in a global test class.
