1. Goal
An olive oil mill presses the olives that its member groves deliver. Show the oil output of each growing region for a period in an ALV list. The mill manager uses the list to compare the regions.
2. Open questions
None.
3. Context
- Table {{P}}GROVE is in package $TMP and contains data. Fields: GROVE_ID (INT4, key), GROVE_NAME (CHAR 30), REGION (CHAR 8), VARIETY (CHAR 10).
- Table {{P}}PRESS is in package $TMP and contains data. Fields: PRESS_ID (INT4, key), GROVE_ID (INT4), PRESS_DATE (DATS), KILOS (INT4), LITRES (DEC 9,2).
4. Contract
- Create the executable program {{P}}OIL_REPORT in package $TMP.
- Selection screen:
- Parameter P_FROM, type DATS, mandatory: the first pressing date to include.
- Select-option S_REG for the growing region.
- Show the result with CL_SALV_TABLE. The output table has these columns with these names: REGION, LITRES, KILOS.
5. Business rules
- Include a pressing only if PRESS_DATE is on or after P_FROM and the region of the grove that delivered the olives is in S_REG.
- LITRES of a region is the sum of the litres of all included pressings.
- KILOS of a region is the sum of the kilos of all included pressings.
- Show one line for each region with at least one included pressing.
- Sort the lines by LITRES, the highest value 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}}GROVE and {{P}}PRESS.
7. Acceptance
- The program is active and has no syntax error.
- The hidden tests pass.
- Write ABAP Unit tests as local test classes in the program.
