+# 1. Goal
+A maple syrup farm collects sap from its groves. The farm must store each sap
+delivery in one database table. Later programs and views read the deliveries
+from this table.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The farm works with several groves. Each grove has a grove number.
+- One delivery belongs to exactly one grove and has exactly one delivery date.
+- The farm measures the sap in litres. The farm measures the sugar content of
+  the sap in degrees Brix.
+- The farm pays the grove for each delivery. The payment is an amount in a
+  currency.
+- All objects are in package $TMP.
+
+# 4. Contract
+- Create the transparent database table {{P}}SYRUP in package $TMP.
+- The table has exactly these fields, in this order:
+  client, delivery_id, grove_id, delivery_date, sap_liters, brix,
+  quality_grade, payout, currency_code.
+
+# 5. Business rules
+1. The table has the fields of the table below. The table below gives the data
+   type, the length and the number of decimals of each field.
+
+   | Field | Data type | Length | Decimals | Key | Not null |
+   | --- | --- | --- | --- | --- | --- |
+   | client | CLNT | 3 | - | yes | yes |
+   | delivery_id | CHAR | 10 | - | yes | yes |
+   | grove_id | CHAR | 8 | - | no | no |
+   | delivery_date | DATS | 8 | - | no | no |
+   | sap_liters | DEC | 9 | 2 | no | no |
+   | brix | DEC | 4 | 1 | no | no |
+   | quality_grade | NUMC | 2 | - | no | no |
+   | payout | CURR | 15 | 2 | no | no |
+   | currency_code | CUKY | 5 | - | no | no |
+
+2. client and delivery_id are the key fields. No other field is a key field.
+3. The key fields are not null.
+4. payout is an amount. The currency of payout is the value of currency_code.
+5. Two rows with the same client and the same delivery_id are not allowed.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP.
+- Out of scope: no other objects.
+
+# 7. Acceptance
+- The table is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests in a global test class. Check the field properties with
+  RTTI and check the table access with CL_OSQL_TEST_ENVIRONMENT.
