+# 1. Goal
+
+A paintball arena records each game round that is played on its fields. A round
+report and an OData service must show the same line for a round. Both use one
+line type. Create this line type as a DDIC structure.
+
+# 2. Open questions
+
+None.
+
+# 3. Context
+
+- The arena plays rounds on numbered fields.
+- A round has a round number, a play date, the number of the field, the name of
+  the visiting team, the number of players, the number of paintballs that the
+  team used, the fee of the round, and the referee.
+- The report and the OData service also show who edited the round last and on
+  which date.
+- All objects are in package $TMP.
+
+# 4. Contract
+
+- Create the DDIC structure {{P}}GAME_ROUND in package $TMP.
+- Create the DDIC structure {{P}}EDIT_STAMP in package $TMP.
+- {{P}}GAME_ROUND has these fields, in this order:
+  ROUND_ID, PLAY_DATE, FIELD_NO, TEAM_NAME, PLAYER_COUNT, PAINTBALLS,
+  ROUND_FEE, REFEREE, LAST_EDITOR, LAST_EDIT_ON.
+- The fields LAST_EDITOR and LAST_EDIT_ON also exist on their own in
+  {{P}}EDIT_STAMP.
+
+# 5. Business rules
+
+1. {{P}}GAME_ROUND is a structure. It has exactly ten fields.
+2. ROUND_ID is a character field. Its length is 10.
+3. PLAY_DATE is a date field. Its type is DATS.
+4. FIELD_NO is a numeric text field. Its length is 2.
+5. TEAM_NAME is a character field. Its length is 20.
+6. PLAYER_COUNT is an integer field. Its type is INT4.
+7. PAINTBALLS is an integer field. Its type is INT4.
+8. ROUND_FEE is a packed number. It has 9 digits and 2 decimal places.
+9. REFEREE is a character field. Its length is 15.
+10. LAST_EDITOR and LAST_EDIT_ON are the last two fields of {{P}}GAME_ROUND.
+11. LAST_EDITOR is a character field. Its length is 12.
+12. LAST_EDIT_ON is a date field. Its type is DATS.
+13. {{P}}EDIT_STAMP is a structure. It has exactly two fields: LAST_EDITOR
+    (character, length 12) and LAST_EDIT_ON (date, type DATS).
+14. {{P}}GAME_ROUND contains the fields of {{P}}EDIT_STAMP at the end. The
+    fields LAST_EDITOR and LAST_EDIT_ON must not be defined twice.
+
+# 6. Constraints
+
+- Release target: ABAP Platform 2025 (SAP_BASIS 816).
+- Coding standards: Clean ABAP.
+- Out of scope: no other objects in package $TMP.
+
+# 7. Acceptance
+
+- Both structures are active and have no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests in a global test class. The tests check the two
+  structures with RTTI.
