+# 1. Goal
+A regional bus company operates depots and routes. Show each route together
+with the depot that operates it. A report and an OData service read the routes.
+The OData service also reads the stops of a route. It uses the association of
+the view in an ABAP SQL path expression.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}DEPOT (bus depot), package $TMP. Key: DEPOT_ID (CHAR 4).
+  Fields: DEPOT_NAME (CHAR 30), CITY (CHAR 20).
+- Table {{P}}ROUTE (bus route), package $TMP. Key: ROUTE_ID (CHAR 6).
+  Fields: DEPOT_ID (CHAR 4), ROUTE_NAME (CHAR 30), DISTANCE_KM (DEC 6,1).
+- Table {{P}}STOP (stop of a route), package $TMP. Key: ROUTE_ID (CHAR 6),
+  STOP_NO (INT4). Fields: STOP_NAME (CHAR 30), DISTANCE_KM (DEC 6,1).
+
+# 4. Contract
+- Create the CDS view entity {{P}}I_STOP in package $TMP.
+  Elements, with these names: ROUTE_ID (key), STOP_NO (key), STOP_NAME,
+  DISTANCE_KM.
+- Create the CDS view entity {{P}}I_ROUTE in package $TMP.
+  Elements, with these names: ROUTE_ID (key), ROUTE_NAME, DEPOT_NAME, CITY,
+  DISTANCE_KM, _STOP.
+- {{P}}I_ROUTE has the association _STOP. The target of _STOP is the view
+  entity {{P}}I_STOP. _STOP is an element of {{P}}I_ROUTE, so that ABAP SQL
+  can use a path expression on _STOP.
+- No authorization check (#NOT_REQUIRED).
+
+# 5. Business rules
+1. {{P}}I_ROUTE shows one row for each route in {{P}}ROUTE.
+2. ROUTE_NAME and DISTANCE_KM are the values of the route.
+3. DEPOT_NAME and CITY are the values of the depot of the route. The depot of
+   a route is the depot with the same DEPOT_ID as the route.
+4. A route whose DEPOT_ID is not in {{P}}DEPOT still appears in the view. In
+   this row DEPOT_NAME and CITY are empty.
+5. _STOP links a route to the rows of {{P}}I_STOP that have the same ROUTE_ID
+   as the route. A route without stops still appears in the view.
+6. {{P}}I_STOP shows one row for each row of {{P}}STOP, with the same element
+   values.
+
+# 6. Constraints
+- Release target: SAP_BASIS 816.
+- Out of scope: do not change {{P}}DEPOT, {{P}}ROUTE and {{P}}STOP.
+- A consumer reads the stops of a route with an ABAP SQL path expression that
+  uses the association _STOP.
+
+# 7. Acceptance
+- The views are active and have no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests with CL_CDS_TEST_ENVIRONMENT in a global test class.
