+# 1. Goal
+A car dealership group sells vehicles through several dealerships. The sales
+office needs a summary of the vehicle sales of one period. It uses the summary
+to compare the dealerships of the group.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}DEALER exists in package $TMP. It contains the dealerships.
+  Fields: DEALER_ID (CHAR 4, key), DEALER_NAME (CHAR 30), CITY (CHAR 20).
+- Table {{P}}VSALE exists in package $TMP. It contains the vehicle sales.
+  Fields: SALE_ID (INT4, key), DEALER_ID (CHAR 4), SALE_DATE (DATS),
+  MODEL_CODE (CHAR 10), PRICE (DEC 15,2).
+
+# 4. Contract
+- Create the executable program {{P}}DEALER_SUM in package $TMP.
+- Selection screen:
+  - Parameter P_FROM, type DATS, mandatory: the first sale date to include.
+  - Parameter P_TO, type DATS, mandatory: the last sale date to include.
+  - Parameter P_CITY, type {{P}}DEALER-CITY, optional: the city of the
+    dealership.
+- Show the result with CL_SALV_TABLE. The output table has these columns with
+  these names: DEALER, CITY, SALES, REVENUE, TOP_MODEL.
+
+# 5. Business rules
+1. Include a sale only if its SALE_DATE is on or after P_FROM and on or before
+   P_TO.
+2. If P_CITY is initial, include the sales of all dealerships. If P_CITY is not
+   initial, include only the sales of dealerships whose CITY equals P_CITY.
+3. Show one line for each dealership that has at least one included sale.
+4. DEALER is the name of the dealership. CITY is the city of the dealership.
+5. SALES is the number of included sales of the dealership.
+6. REVENUE is the sum of the PRICE values of the included sales.
+7. TOP_MODEL is the model code with the highest total price in the dealership.
+   If two model codes of the dealership have the same total price, TOP_MODEL is
+   the code that comes first in ascending alphabetical order.
+8. Sort the lines by REVENUE, the highest revenue first. If two dealerships have
+   the same revenue, sort them by DEALER in ascending order.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP. A method has fewer than 40 statements. Do not
+  access the database inside a loop.
+- Out of scope: do not change {{P}}DEALER and {{P}}VSALE.
+
+# 7. Acceptance
+- The program is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests as local test classes in the program.
