+# 1. Goal
+Refactor the legacy report {{P}}BAKERY_BILL_OLD in package $TMP. A bakery bills
+its shops for the bread and the rolls that it delivered in a period. The report
+must keep its behavior and become maintainable.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The report {{P}}BAKERY_BILL_OLD is active in package $TMP. It is legacy code.
+- The report reads the tables {{P}}SHOP and {{P}}DELIV. Both tables contain data.
+- The report shows an ALV list.
+
+# 4. Contract
+- Keep the report {{P}}BAKERY_BILL_OLD in package $TMP. Keep the name.
+- Keep the selection screen:
+  - Parameter P_FROM, type DATS, mandatory: the first delivery date to include.
+  - Parameter P_TO, type DATS, mandatory: the last delivery date to include.
+  - Select-option S_SHOP for the shop.
+- Keep the ALV output. The output table has these columns, with these names:
+  SHOP_ID, SHOP_NAME, LOAVES, ROLLS, TOTAL.
+
+# 5. Business rules
+The behavior stays the same. The legacy code contains the rules. Read the
+legacy code and keep every rule, every filter and every value. Do not change
+the selection screen, the output columns or the result rows.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP.
+- Quality goals:
+  - Read each of the two tables with one database access.
+  - Do not use a nested loop over the two tables. The runtime must grow with
+    the number of rows, not with the product of the rows.
+  - Do not use obsolete language elements. No FORM routines, no header-line
+    tables, no SELECT *.
+  - Put the logic in a local class. Keep every method below 40 statements.
+- Out of scope: do not change the tables {{P}}SHOP and {{P}}DELIV.
+
+# 7. Acceptance
+- The report is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests as local test classes in the program.
