# 1. Goal
|
|
Show the energy that each charging station has delivered. A dashboard and an OData service will read the energy totals, so the calculation must be in the database, in a CDS view.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- Table {{P}}STATION (charging station), package $TMP. Key: STATION_ID (CHAR 10). Fields: CITY (CHAR 40), CAPACITY_KW (DEC 5,1).
|
|
- Table {{P}}SESSION (charging session), package $TMP. Key: SESSION_ID (CHAR 10). Fields: STATION_ID (CHAR 10), START_DATE (DATS), START_TIME (TIMS), ENERGY_KWH (DEC 9,2), STATUS (CHAR 1). STATUS can be 'C' (completed), 'A' (aborted), or 'R' (running).
|
|
|
|
# 4. Contract
|
|
- Create the CDS view entity {{P}}I_STATION_ENERGY in package $TMP.
|
|
- Elements, with these names: STATION_ID (key), CITY, SESSION_COUNT, TOTAL_ENERGY.
|
|
- No authorization check (#NOT_REQUIRED).
|
|
|
|
# 5. Business rules
|
|
1. Show one row for each charging station.
|
|
2. SESSION_COUNT is the number of charging sessions of the station.
|
|
3. TOTAL_ENERGY is the sum of the energy of the charging sessions of the station, in kWh with 2 decimals.
|
|
|
|
# 6. Constraints
|
|
- Release target: 8.16 (SAP_BASIS 816).
|
|
- Coding standards: Clean ABAP.
|
|
- Out of scope: do not change {{P}}STATION and {{P}}SESSION.
|
|
|
|
# 7. Acceptance
|
|
- The view is active and has no syntax error.
|
|
- Write ABAP Unit tests with CL_CDS_TEST_ENVIRONMENT in a global test class.
