# 1. Goal
|
|
Show the weight check of each container at a container terminal. A report and an
|
|
OData service will read the check, so the calculation must be in the database,
|
|
in a CDS view.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- Table {{P}}CONT (container master), package $TMP. Key: CONT_ID (CHAR 10).
|
|
Fields: CUSTOMER (CHAR 10), DECL_KG (DEC 15,2, declared weight in kilograms),
|
|
MAX_KG (DEC 15,2, maximum permitted weight in kilograms).
|
|
- Table {{P}}WEIGH (weighbridge record), package $TMP. Key: CONT_ID (CHAR 10).
|
|
Field: MEAS_KG (DEC 15,2, measured weight in kilograms).
|
|
|
|
# 4. Contract
|
|
- Create the CDS view entity {{P}}I_CONT_WEIGHT in package $TMP.
|
|
- Elements, with these names: CONT_ID (key), CUSTOMER, DECL_KG, MEAS_KG,
|
|
DEVIATION_KG, DEVIATION_PCT, STATUS.
|
|
- No authorization check (#NOT_REQUIRED).
|
|
|
|
# 5. Business rules
|
|
1. Show one row for each container that has a weighbridge record. Do not show a
|
|
container without a weighbridge record.
|
|
2. DEVIATION_KG is the difference between MEAS_KG and DECL_KG, without a sign.
|
|
It is always positive or zero and it has 2 decimals.
|
|
3. DEVIATION_PCT is DEVIATION_KG as a percentage of DECL_KG. It has 2 decimals.
|
|
4. STATUS is 'HOLD' if MEAS_KG is greater than MAX_KG.
|
|
5. STATUS is 'WARN' if rule 4 is not true and DEVIATION_PCT is greater than 5.
|
|
6. STATUS is 'LOAD' in all other cases.
|
|
7. DECL_KG is always greater than zero.
|
|
|
|
# 6. Constraints
|
|
- Release target: 8.16.
|
|
- Use Clean ABAP. Keep every method below 40 statements.
|
|
- Out of scope: do not change {{P}}CONT and {{P}}WEIGH.
|
|
|
|
# 7. Acceptance
|
|
- The view is active and has no syntax error.
|
|
- The hidden tests pass.
|
|
- Write ABAP Unit tests with CL_CDS_TEST_ENVIRONMENT in a global test class.
