# 1. Goal
|
|
|
|
A hospital wants a report about the bed days of its wards. The report shows,
|
|
for each ward, the number of admissions in a period, the bed days, and the cost
|
|
of these bed days. The hospital management compares the wards with this report.
|
|
|
|
# 2. Open questions
|
|
|
|
None.
|
|
|
|
# 3. Context
|
|
|
|
- The table {{P}}ADMIT exists in package $TMP. The table contains data. The
|
|
fields are:
|
|
- ADM_ID: INT4, key. The admission ID.
|
|
- WARD: CHAR 4. The ward.
|
|
- ADMIT_DATE: DATS. The admission date.
|
|
- DISCHARGE_DATE: DATS. The discharge date. The field is initial while the
|
|
patient is still in the ward.
|
|
- DAILY_RATE: DEC 15,2. The cost of one bed day in this ward.
|
|
|
|
# 4. Contract
|
|
|
|
- Create the executable program {{P}}WARD_STAY in package $TMP.
|
|
- Selection screen:
|
|
- Parameter P_FROM, type DATS, mandatory. The first admission date to include.
|
|
- Parameter P_TO, type DATS, mandatory. The last admission date to include.
|
|
- Select-option S_WARD for the ward.
|
|
- Show the result with CL_SALV_TABLE. The output table has exactly these columns
|
|
with these names and types:
|
|
- WARD: type {{P}}ADMIT-WARD.
|
|
- ADMISSIONS: type I.
|
|
- BED_DAYS: type I.
|
|
- TOTAL_COST: type {{P}}ADMIT-DAILY_RATE.
|
|
|
|
# 5. Business rules
|
|
|
|
1. Include an admission only if ADMIT_DATE is on or after P_FROM, ADMIT_DATE is
|
|
on or before P_TO, and WARD is in S_WARD.
|
|
2. The bed days of one admission are DISCHARGE_DATE minus ADMIT_DATE.
|
|
3. If DISCHARGE_DATE of an admission is initial, use P_TO as the discharge date
|
|
of this admission.
|
|
4. The cost of one admission is the bed days of the admission multiplied by
|
|
DAILY_RATE.
|
|
5. Show one line for each ward that has at least one included admission.
|
|
6. ADMISSIONS is the number of included admissions of the ward.
|
|
7. BED_DAYS is the sum of the bed days of the included admissions of the ward.
|
|
8. TOTAL_COST is the sum of the costs of the included admissions of the ward.
|
|
9. Sort the lines by TOTAL_COST, the highest total first.
|
|
|
|
# 6. Constraints
|
|
|
|
- Release target: 7.40 SP05. Do not use ABAP syntax that is newer than
|
|
7.40 SP05. Examples of newer syntax are table expressions, FOR or REDUCE in
|
|
constructor expressions, string aggregation, UNION, and WITH.
|
|
- Coding standards: Clean ABAP. Read the admissions with one database access.
|
|
- Out of scope: do not change the table {{P}}ADMIT.
|
|
|
|
# 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.
