1. Goal

Show a comparison of the planned and the actual visitor numbers of the exhibitions of a museum. The museum director uses the list to see which exhibitions reached their plan and how many visitors are still missing.

2. Open questions

None.

3. Context

• Table {{P}}EXHIB exists in package $TMP. It contains the plan of the exhibitions. It contains data. Fields: EXHIB_ID (CHAR 6, key), EXHIB_NAME (CHAR 30), PLAN_VIS (INT4).
• Table {{P}}VISIT exists in package $TMP. It contains the daily visitor numbers. It contains data. Fields: VISIT_ID (INT4, key), EXHIB_ID (CHAR 6), VISIT_DATE (DATS), VISITORS (INT4).

4. Contract

• Create the executable program {{P}}EXHIB_CMP in package $TMP.
• Selection screen:
  • Parameter P_FROM, type DATS, mandatory: the first visit date to include.
  • Parameter P_TO, type DATS, mandatory: the last visit date to include.
  • Select-option S_EXHIB for the exhibition ID.
• Show the result with CL_SALV_TABLE. The output table has these columns, with these names: EXHIB_ID, EXHIB_NAME, PLAN_VIS, ACT_VIS, GAP. PLAN_VIS, ACT_VIS and GAP are integers.

5. Business rules

1. Include an exhibition only if its EXHIB_ID is in S_EXHIB.
2. Include a visit only if its EXHIB_ID is in S_EXHIB and its VISIT_DATE is on or after P_FROM and on or before P_TO.
3. Show one line for each exhibition that has a plan row or at least one included visit.
4. ACT_VIS is the sum of the VISITORS of the included visits of the exhibition. If the exhibition has no included visit, ACT_VIS is 0.
5. PLAN_VIS is the planned number of the exhibition. If the exhibition has no plan row, PLAN_VIS is 0 and EXHIB_NAME is empty.
6. GAP is PLAN_VIS minus ACT_VIS if ACT_VIS is less than PLAN_VIS. In all other cases GAP is 0.
7. Sort the lines by ACT_VIS, the highest first. If two lines have the same ACT_VIS, sort them by EXHIB_ID in ascending order.

6. Constraints

• Release target: 8.16.
• Coding standards: Clean ABAP. Read each table with one database access.
• Out of scope: do not change {{P}}EXHIB and {{P}}VISIT.

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.
