# 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
|
|
1. Include a session only if SESSION_DATE is on or after P_FROM and on or before
|
|
P_TO.
|
|
2. Show one line for each station that has at least one included session.
|
|
3. 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.
|
|
4. Sort the lines by TOTAL_KWH, the highest total first.
|
|
5. 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.
