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.
