+# 1. Goal
+Show the studio fee of each customer in an ALV list. The studio uses the list to
+bill its customers for a period.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The table {{P}}STUDIO exists in package $TMP. It contains the recording
+  sessions of the studio and it contains data.
+  Fields: REC_ID (INT4, key), CUSTOMER (CHAR 10), REC_DATE (DATS),
+  TRACKS (INT4), FEE (DEC 15,2).
+
+# 4. Contract
+- Create the executable program {{P}}STUDIO_BILL in package $TMP.
+- Selection screen:
+  - Parameter P_FROM, type DATS, mandatory: the first recording date to include.
+  - Parameter P_MIN, type P LENGTH 15 DECIMALS 2, mandatory: the minimum total
+    fee.
+  - Select-option S_CUST for the customer.
+- Show the result with CL_SALV_TABLE. The output table has these columns with
+  these names:
+  - CUSTOMER: the customer.
+  - SESSIONS: the number of included recording sessions of the customer.
+  - TRACKS: the sum of TRACKS of the included sessions.
+  - FEE: the sum of FEE of the included sessions.
+
+# 5. Business rules
+1. Include a recording session only if REC_DATE is on or after P_FROM, CUSTOMER
+   is in S_CUST, and TRACKS is greater than zero.
+2. Show one line for each customer that has at least one included session.
+3. Show only the customers whose total fee is on or after P_MIN.
+4. Sort the lines by FEE, the highest fee first.
+
+# 6. Constraints
+- Release target: 7.58.
+- Coding standards: Clean ABAP. Read the data with one database access.
+- Out of scope: do not change the table {{P}}STUDIO.
+
+# 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.
