+# 1. Goal
+Fix the CDS view entity {{P}}I_DIVE_STATS in package $TMP. The view shows the
+diving activity of each diver. The operations team reports two symptoms:
+- The view shows one row for each dive of a diver, not one row for each diver.
+- DIVE_COUNT is always 1.
+The view must show one row for each diver, and DIVE_COUNT must show the number of
+dives of the diver.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}DIVER (diver), package $TMP. Key: DIVER_ID (CHAR 10).
+  Field: DIVER_NAME (CHAR 40).
+- Table {{P}}SITE (dive site), package $TMP. Key: SITE_ID (CHAR 10).
+  Fields: SITE_NAME (CHAR 40), DEPTH_M (INT4, depth of the site in metres).
+- Table {{P}}DIVE (dive), package $TMP. Key: DIVE_ID (CHAR 10).
+  Fields: DIVER_ID (CHAR 10), SITE_ID (CHAR 10), DIVE_DATE (DATS).
+- The CDS view entity {{P}}I_DIVE_STATS exists in package $TMP and is active.
+- The class {{P}}SEED_DIVE fills the three tables with test data and shows the
+  view.
+
+# 4. Contract
+- Fix the CDS view entity {{P}}I_DIVE_STATS in package $TMP.
+- Elements, with these names: DIVER_ID (key), DIVER_NAME, DIVE_COUNT, DEEPEST_M.
+- No authorization check (#NOT_REQUIRED).
+
+# 5. Business rules
+1. The view shows one row for each diver that has at least one dive. A diver
+   without dives does not appear.
+2. DIVE_COUNT is the number of dives of the diver. A dive whose site is not in
+   {{P}}SITE still counts as one dive.
+3. DEEPEST_M is the greatest DEPTH_M of the sites of the dives of the diver. A
+   dive without a site adds nothing to DEEPEST_M.
+4. DIVER_NAME is the name of the diver.
+5. All other behavior stays the same.
+
+# 6. Constraints
+- Release target: SAP_BASIS 816.
+- Out of scope: do not change {{P}}DIVER, {{P}}SITE, {{P}}DIVE and
+  {{P}}SEED_DIVE.
+- Coding standards: Clean ABAP.
+
+# 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.
