+# 1. Goal
+The CDS view entity {{P}}I_PO_VALUE shows the value of each purchase order of
+an electronics company. The view gives a wrong result. When two purchase orders
+have the same order number in two different fiscal years, the view shows a
+total that is too high and an item count that is too high for both orders.
+Fix the view. Each row must use only the items of its own purchase order.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The CDS view entity {{P}}I_PO_VALUE is in package $TMP. It is active. It reads
+  the tables {{P}}PO_HEAD and {{P}}PO_ITEM.
+- Table {{P}}PO_HEAD (purchase order header), package $TMP.
+  Key: PO_NO (CHAR 10), FISCAL_YEAR (CHAR 4).
+  Fields: SUPPLIER (CHAR 10), PO_DATE (DATS).
+- Table {{P}}PO_ITEM (purchase order item), package $TMP.
+  Key: PO_NO (CHAR 10), FISCAL_YEAR (CHAR 4), ITEM_NO (INT4).
+  Fields: QUANTITY (INT4), PRICE (DEC 15,2, the price for one unit).
+- An order number is unique only inside one fiscal year. Two purchase orders can
+  have the same PO_NO in two different fiscal years.
+- Read the current source of the view before you change it.
+
+# 4. Contract
+- Fix the CDS view entity {{P}}I_PO_VALUE in package $TMP. The name of the view
+  and the names of the elements do not change.
+- Elements: PO_NO (key), FISCAL_YEAR (key), SUPPLIER, ITEM_COUNT, TOTAL_VALUE.
+- The authorization check stays #NOT_REQUIRED.
+
+# 5. Business rules
+1. A purchase order is identified by PO_NO together with FISCAL_YEAR.
+2. A row uses only the items of its own purchase order. Items of another
+   purchase order with the same PO_NO must not change ITEM_COUNT and must not
+   change TOTAL_VALUE.
+3. All other behavior of the view stays the same.
+
+# 6. Constraints
+- Release target: 8.16 (SAP_BASIS 816, ABAP Platform 2025).
+- Coding standards: Clean ABAP. Keep the view simple.
+- Out of scope: do not change the tables {{P}}PO_HEAD and {{P}}PO_ITEM.
+
+# 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.
