# 1. Goal
Show how much each bike of a bike-sharing fleet is used. The operations team
needs the heavily used bikes, so that it can plan maintenance. A report and an
OData service will read the usage figures. Therefore the calculation must run in
the database, in a CDS view.

# 2. Open questions
None.

# 3. Context
- Table {{P}}BIKE holds the bikes, package $TMP. Key: BIKE_ID (CHAR 10).
  Fields: STATION (CHAR 10), BIKE_TYPE (CHAR 4).
- Table {{P}}RIDE holds the rides, package $TMP. Key: RIDE_ID (CHAR 10).
  Fields: BIKE_ID (CHAR 10), RIDE_DATE (DATS), DISTANCE_KM (DEC 5,1, the
  distance of the ride in kilometres).

# 4. Contract
- Create the CDS view entity {{P}}I_BIKE_USE in package $TMP.
- The view has these elements, with these names:
  BIKE_ID (key), STATION, RIDE_COUNT, TOTAL_DISTANCE.
- Use no authorization check (#NOT_REQUIRED).

# 5. Business rules
1. The view shows one row for each bike that has at least one ride. A bike
   without rides is not shown.
2. RIDE_COUNT is the number of rides of the bike.
3. TOTAL_DISTANCE is the sum of DISTANCE_KM of all rides of the bike.
4. The view shows only the bikes whose total distance is more than 50.0
   kilometres. A bike with a total distance of exactly 50.0 kilometres is not
   shown.

# 6. Constraints
- Release target: 7.58.
- Coding standards: Clean ABAP.
- Out of scope: do not change {{P}}BIKE and {{P}}RIDE.

# 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.
