1. Goal
Show the energy that each charging station of a charging network delivered in a period in an ALV list. The network operator uses the list to compare the stations.
2. Open questions
None.
3. Context
- Table {{P}}CHARGE exists in package $TMP. It contains data. Fields: SESSION_ID (INT4, key), STATION (CHAR 10), SESSION_DATE (DATS), ENERGY_KWH (DEC 15,2).
4. Contract
- Create the executable program {{P}}CHARGE_STAT in package $TMP.
- Selection screen:
- Parameter P_FROM, type DATS, mandatory: the first session date to include.
- Parameter P_TO, type DATS, mandatory: the last session date to include.
- Show the result with CL_SALV_TABLE. The output table has these columns, with these names: STATION, TOTAL_KWH, SESSIONS.
5. Business rules
- Include a session only if SESSION_DATE is on or after P_FROM and on or before P_TO.
- Show one line for each station that has at least one included session.
- TOTAL_KWH is the sum of ENERGY_KWH of the included sessions of the station. SESSIONS is the number of included sessions of the station.
- Sort the lines by TOTAL_KWH, the highest total first.
- Sort the lines by TOTAL_KWH, the lowest total first.
6. Constraints
- Release target: 8.16.
- Coding standards: Clean ABAP. Read the data with one database access.
- Out of scope: do not change {{P}}CHARGE.
7. Acceptance
- The program is active and has no syntax error.
- The list shows one line for each station that has at least one included session.
- Write ABAP Unit tests as local test classes in the program.
