# 1. Goal
|
|
Show the workload of each tutor of a music school. A report and an OData
|
|
service will read the workload, so the calculation must be in the database,
|
|
in a CDS view.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- Table {{P}}TUTOR (tutor master data), package $TMP. Key: TUTOR_ID (CHAR 10).
|
|
Fields: TUTOR_NAME (CHAR 30), SUBJECT (CHAR 20).
|
|
- Table {{P}}LESSON (the lessons that the tutors give), package $TMP.
|
|
Key: LESSON_ID (CHAR 10). Fields: TUTOR_ID (CHAR 10), LESSON_DATE (DATS),
|
|
DUR_MIN (INT4, the length of the lesson in minutes).
|
|
|
|
# 4. Contract
|
|
- Create the CDS view entity {{P}}I_TUTOR_LOAD in package $TMP.
|
|
- Elements, with these names: TUTOR_ID (key), TUTOR_NAME, LESSON_COUNT,
|
|
TOTAL_MINUTES.
|
|
- No authorization check (#NOT_REQUIRED).
|
|
|
|
# 5. Business rules
|
|
1. Count only lessons with DUR_MIN greater than 0. A lesson with DUR_MIN = 0
|
|
is not a lesson of this view. It does not count and it does not add minutes.
|
|
2. Show one row for each tutor who has at least 3 lessons. Do not show a tutor
|
|
with fewer than 3 lessons. Do not show a tutor without lessons.
|
|
3. LESSON_COUNT is the number of lessons of the tutor.
|
|
4. TOTAL_MINUTES is the sum of the DUR_MIN values of all lessons of the tutor.
|
|
5. TUTOR_NAME is the name of the tutor.
|
|
|
|
# 6. Constraints
|
|
- Release target: 8.16 (SAP_BASIS 816).
|
|
- Coding standards: Clean ABAP.
|
|
- Out of scope: do not change {{P}}TUTOR and {{P}}LESSON.
|
|
|
|
# 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.
