# 1. Goal
|
|
Show the number of tracks and the playtime of each album. A report and an OData
|
|
service will read these figures, so the calculation must be in the database, in a
|
|
CDS view.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- Table {{P}}ALBUM in package $TMP holds the albums. One row is one album.
|
|
- Table {{P}}TRACK in package $TMP holds the tracks. One row is one track of an
|
|
album. A track has a duration in seconds.
|
|
- The fields of the two tables are not part of this document. Read the two tables
|
|
in the system to find their fields and types.
|
|
|
|
# 4. Contract
|
|
- Create the CDS view entity {{P}}I_ALBUM_STATS in package $TMP.
|
|
- Elements, with these names: ALBUM_ID (key), TITLE, TRACK_COUNT, TOTAL_SECONDS,
|
|
LONGEST_SECONDS.
|
|
- No authorization check (#NOT_REQUIRED).
|
|
|
|
# 5. Business rules
|
|
1. Show one row for each album that has at least one track. Do not show an album
|
|
without tracks.
|
|
2. TRACK_COUNT is the number of tracks of the album.
|
|
3. TOTAL_SECONDS is the total duration of all tracks of the album, in seconds.
|
|
4. LONGEST_SECONDS is the duration of the longest track of the album, in seconds.
|
|
5. TITLE is the title of the album.
|
|
6. A duration is a whole number of seconds. Do not change it and do not round it.
|
|
|
|
# 6. Constraints
|
|
- Release target: 8.16.
|
|
- Coding standards: Clean ABAP.
|
|
- Out of scope: do not change {{P}}ALBUM and {{P}}TRACK.
|
|
|
|
# 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.
