# 1. Goal
The CDS view entity {{P}}I_HONEY_YIELD shows the honey yield of each apiary of a
beekeeping cooperative. The view is active, but its numbers are wrong. Fix the
view in place. A report and an OData service read the view.

# 2. Open questions
None.

# 3. Context
- Table {{P}}APIARY (apiary header), package $TMP. Key: APIARY_ID (CHAR 10).
  Fields: BEEKEEPER (CHAR 10), REGION (CHAR 4), HIVE_COUNT (INT4).
- Table {{P}}HONEY (honey harvest), package $TMP. Key: APIARY_ID (CHAR 10),
  HARVEST_NO (INT4). Fields: REGION (CHAR 4, region of the apiary at the time
  of the harvest), HARVEST_DATE (DATS), KILOGRAMS (DEC 15,2).
- The view {{P}}I_HONEY_YIELD is in package $TMP and is active. The name, the
  package and the element names stay the same.

# 4. Contract
- Fix the CDS view entity {{P}}I_HONEY_YIELD in package $TMP. Do not create a
  new view.
- Elements, with these names: APIARY_ID (key), BEEKEEPER, REGION, HARVEST_COUNT,
  TOTAL_KG.
- No authorization check (#NOT_REQUIRED).

# 5. Business rules
The users report these symptoms:
1. TOTAL_KG is too high for several apiaries. Expected: TOTAL_KG is the sum of
   the KILOGRAMS of the harvests of that apiary only.
2. HARVEST_COUNT is too high for the same apiaries. Expected: HARVEST_COUNT is
   the number of harvest records of that apiary only.
3. The list also shows apiaries that delivered no honey. Expected: the view
   shows one row for each apiary that has at least one record in {{P}}HONEY. An
   apiary without harvest records is not shown.
All other behavior stays the same. In particular:
4. BEEKEEPER is the beekeeper of the apiary, and REGION is the region of the
   apiary.
5. An apiary with harvest records has exactly one row, also when no other apiary
   of its region has harvest records.

# 6. Constraints
- Release target: ABAP Platform 2025 (SAP_BASIS 816).
- Coding standards: Clean ABAP. The view must be active and must not have a
  syntax error. ATC must not report findings of priority 1 or priority 2.
- Out of scope: do not change {{P}}APIARY and {{P}}HONEY. Do not change the name
  of the view or the names of its elements.

# 7. Acceptance
- The view {{P}}I_HONEY_YIELD 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.
