+# 1. Goal
+The bowling alley "Strike Lane" needs a database table for its lane bookings.
+The booking desk will read the bookings with ABAP SQL and later with a CDS view.
+In their daily work the staff use the words hours, mode, order, date, count,
+group and value. These words are reserved words in ABAP SQL. The new table must
+therefore use safe field names.
+
+# 2. Open questions
+None.
+
+# 3. Context
+The bowling alley has 12 lanes. A guest books one lane for a time slot. The
+booking desk writes one row for each booking into the new table. The table is
+the first object of the bowling alley in package $TMP. No other object exists.
+
+# 4. Contract
+Create the transparent database table {{P}}BOWL in package $TMP. The table has
+the following fields, in this order, with these names:
+
+- client: CLNT 3, key
+- booking_id: CHAR 10, key
+- lane_no: NUMC 2, key
+- play_hours: DEC 4,2
+- game_mode: CHAR 1
+- order_no: CHAR 10
+- play_date: DATS
+- player_count: INT4
+- league_code: CHAR 4
+- price_value: DEC 11,2
+
+# 5. Business rules
+1. The key of the table is the combination of client, booking_id and lane_no.
+   No other field is a key field.
+2. play_hours is the booked time in hours. It has 4 characters and 2 decimals.
+3. game_mode is a single character. 'N' means a normal game, 'L' means a league
+   game.
+4. order_no is the number of the order that the guest paid at the counter. It
+   has 10 characters.
+5. play_date is the day of the booking.
+6. player_count is the number of players on the lane. It is a whole number.
+7. league_code is the code of the league. It has 4 characters. For a normal
+   game the field is empty.
+8. price_value is the value of the booking in the local currency. It has 11
+   characters and 2 decimals.
+9. No field name is a reserved word of ABAP SQL. The table must not have a
+   field with the name hours, mode, order, date, count, group or value.
+10. The booking number is unique for one client and one lane. A second INSERT
+    with the same client, the same booking number and the same lane number does
+    not change the table and gives sy-subrc = 4.
+
+# 6. Constraints
+- Release target: ABAP Platform 2025 (SAP_BASIS 816). Package $TMP. No
+  transport.
+- Use only the built-in Dictionary types abap.clnt, abap.char, abap.numc,
+  abap.dats, abap.int4 and abap.dec. Do not use abap.curr or abap.quan.
+- Write the table as a DDL source with the annotations @EndUserText.label,
+  @AbapCatalog.enhancement.category : #NOT_EXTENSIBLE,
+  @AbapCatalog.tableCategory : #TRANSPARENT, @AbapCatalog.deliveryClass : #A
+  and @AbapCatalog.dataMaintenance : #RESTRICTED. Declare the key fields as
+  not null.
+- Do not create any other repository object than the table and your own test
+  class.
+- Out of scope: a CDS view, a report, a function module and a class with
+  business logic.
+
+# 7. Acceptance
+- The table {{P}}BOWL is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests with CL_OSQL_TEST_ENVIRONMENT in a global test class.
