+# 1. Goal
+Show the subscriptions of each magazine in an ALV list. The publisher uses the
+list to compare the magazines for a period.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}SUBS exists in package $TMP. It contains data.
+  Fields: SUBS_ID (INT4, key), MAGAZINE (CHAR 12), SUB_STATUS (CHAR 1),
+  START_DATE (DATS), MONTHLY_FEE (DEC 15,2).
+- SUB_STATUS is 'A' for an active subscription and 'C' for a cancelled
+  subscription.
+
+# 4. Contract
+- Create the executable program {{P}}SUBS_SUM in package $TMP.
+- Selection screen:
+  - Parameter P_FROM, type DATS, mandatory: the first start date to include.
+  - Select-option S_MAG for the magazine.
+- Show the result with CL_SALV_TABLE. The output table has these columns, with
+  these names: MAGAZINE, NUM_SUBS (number of included subscriptions),
+  REVENUE (sum of MONTHLY_FEE).
+
+# 5. Business rules
+1. Include a subscription only if SUB_STATUS is 'A', START_DATE is on or after
+   P_FROM, and MAGAZINE is in S_MAG.
+2. Show one line for each magazine that has at least two included subscriptions.
+3. Sort the lines by REVENUE, the highest revenue first.
+
+# 6. Constraints
+- Release target: 7.40 SP05. Use only syntax that this release supports.
+- Coding standards: Clean ABAP. Read the data with one database access.
+- Out of scope: do not change {{P}}SUBS.
+
+# 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.
