+# 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.
