1. Goal

Show the sales total for each region in an ALV list. The sales team uses the list to compare regions for a period.

2. Open questions

None.

3. Context

• Table {{P}}SALE exists in package $TMP. It contains data. Fields: SALE_ID (INT4, key), REGION (CHAR 4), SALE_DATE (DATS), AMOUNT (DEC 15,2).

4. Contract

• Create the executable program {{P}}SALES_SUM in package $TMP.
• Selection screen:
  • Parameter P_FROM, type DATS, mandatory: the first sale date to include.
  • Select-option S_REG for the region.
• Show the result with CL_SALV_TABLE. The output table has these columns, with these names: REGION, TOTAL (sum of AMOUNT), COUNT (number of sales).

5. Business rules

1. Include a sale only if SALE_DATE is on or after P_FROM and REGION is in S_REG.
2. Show one line for each region that has at least one included sale.
3. Sort the lines by TOTAL, the highest total first.

6. Constraints

• Release target: 7.58.
• Coding standards: Clean ABAP. Read the data with one database access.
• Out of scope: do not change {{P}}SALE.

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.
