+# 1. Goal
+The farm shop of a cooperative sells its own vegetables, fruit and dairy goods.
+The report {{P}}FARM_SHOP_OLD shows the turnover of one day, grouped by product
+group. The report is in production, but its code is outdated and hard to
+maintain. Refactor the report in place: same name, same selection screen, same
+output. The behavior stays the same.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- {{P}}FARM_SHOP_OLD is an executable program in package $TMP. It is active.
+- The report reads the tables {{P}}GOODS and {{P}}GDSALE. Both tables are in
+  package $TMP and contain data.
+  - {{P}}GOODS: GOODS_ID (CHAR 4, key), GRP_CODE (CHAR 4), UNIT_PRICE (DEC 15,2).
+  - {{P}}GDSALE: SALE_ID (INT4, key), GOODS_ID (CHAR 4), SALE_DAY (DATS),
+    QTY (INT2), SALE_STATE (CHAR 1).
+- The report writes the result with CL_SALV_TABLE.
+- The legacy implementation is the only specification of the rules. Read it.
+
+# 4. Contract
+- The program {{P}}FARM_SHOP_OLD stays in package $TMP. Do not rename it.
+- The selection screen stays the same:
+  - Parameter P_DAY, type DATS, mandatory.
+  - Select-option S_GRP for the product group.
+- The ALV list keeps these columns, with these names:
+  GRP_CODE, SALES, TURNOVER, PCT_SHARE.
+
+# 5. Business rules
+The behavior of the report stays the same. The legacy code is the only
+specification. Keep every result exactly as it is today: the same rows, the
+same values, the same order, the same filters.
+
+# 6. Constraints
+- Release target: 8.16 (SAP_BASIS 816, ABAP Platform 2025).
+- Coding standards: Clean ABAP. Methods below 40 statements. No obsolete
+  language elements. No database access inside a loop. No header-line tables.
+  Never mix old and new ABAP SQL syntax in one statement.
+- Out of scope: do not change {{P}}GOODS and {{P}}GDSALE. Do not change the
+  selection screen. Do not change the names of the output columns.
+
+# 7. Acceptance
+- {{P}}FARM_SHOP_OLD is active and has no syntax error.
+- The behavior of the report is unchanged.
+- The hidden tests pass.
+- ATC reports no finding of priority 1 or 2.
+- Write ABAP Unit tests as local test classes in the program.
