+# 1. Goal
+A vineyard cooperative collects the harvest reports of its members. The
+cooperative needs one evaluation of the harvest for each grape variety. A
+planning program calls the evaluation before it plans the transport of the
+grapes to the winery.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The interface {{P}}IF_HARVEST exists in package $TMP. It is active.
+- The interface contains the data types for the harvest reports, for the member
+  master data, and for the result. Read the interface before you start to work.
+- A harvest report has a member, a grape variety, and a quantity in kilograms.
+- The member master data has a member ID and a member name.
+
+# 4. Contract
+- Create the class {{P}}HARVEST_EVALUATOR in package $TMP.
+- The class is public and final. It has a public constructor without
+  parameters.
+- The class has one public method:
+  EVALUATE
+    IMPORTING it_report        TYPE {{P}}IF_HARVEST=>TT_REPORT
+              it_member        TYPE {{P}}IF_HARVEST=>TT_MEMBER
+    RETURNING VALUE(rt_result) TYPE {{P}}IF_HARVEST=>TT_RESULT.
+- Do not add other public methods.
+
+# 5. Business rules
+A harvest report is countable when rule 1 and rule 2 are true.
+1. The member_id of the report occurs in it_member. A member_id occurs at most
+   one time in it_member.
+2. The quantity_kg of the report is greater than 0.
+3. Group the countable reports by variety. Create one result row for each
+   variety that has at least one countable report.
+4. The total_kg of a result row is the sum of the quantity_kg of all countable
+   reports of the variety.
+5. The member_count of a result row is the number of different member_id
+   values in the countable reports of the variety.
+6. Sort the result rows by total_kg in descending order. When two rows have the
+   same total_kg, sort these rows by variety in ascending order.
+7. When no report is countable, return an empty table.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change {{P}}IF_HARVEST.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
