+# 1. Goal
+Give the total value of each order. A report and an OData service will read the
+totals, so the calculation must be in the database, in a CDS view.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}ORD (order header), package $TMP. Key: ORDER_ID (CHAR 10).
+  Fields: CUSTOMER (CHAR 10), ORDER_DATE (DATS).
+- Table {{P}}ITM (order item), package $TMP. Key: ORDER_ID (CHAR 10), ITEM_NO (INT4).
+  Fields: PRODUCT (CHAR 10), QUANTITY (INT4), PRICE (DEC 15,2, price for one unit).
+
+# 4. Contract
+- Create the CDS view entity {{P}}I_ORDER_TOTAL in package $TMP.
+- Elements, with these names: ORDER_ID (key), CUSTOMER, ITEM_COUNT, TOTAL_AMOUNT.
+- No authorization check (#NOT_REQUIRED).
+
+# 5. Business rules
+1. Show one row for each order that has at least one item. Do not show an order
+   without items.
+2. ITEM_COUNT is the number of items of the order.
+3. TOTAL_AMOUNT is the sum of QUANTITY multiplied by PRICE for all items of the
+   order, with 2 decimals.
+
+# 6. Constraints
+- Release target: 7.58.
+- Out of scope: do not change {{P}}ORD and {{P}}ITM.
+
+# 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.
