+# 1. Goal
+The mobile bicycle repair service "Bike Doctor" repairs bicycles at the homes of
+its customers. The office needs a list of the repair jobs of one day. Each line
+shows the job, the customer, the mechanic, the number of spare parts and the
+total price of the parts. The office uses the list to check the daily work.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}MECH is in package $TMP. It contains the mechanics.
+  Fields: MECH_ID (CHAR 6, key), MECH_NAME (CHAR 40).
+- Table {{P}}JOBHDR is in package $TMP. It contains the repair jobs.
+  Fields: JOB_ID (INT4, key), JOB_DATE (DATS), CUSTOMER (CHAR 40),
+  MECH_ID (CHAR 6).
+- Table {{P}}JOBITM is in package $TMP. It contains the spare parts that the
+  mechanic used for a job.
+  Fields: JOB_ID (INT4, key), ITEM_NO (INT4, key), SPARE_PART (CHAR 20),
+  QTY (INT4), PRICE (DEC 15,2).
+- The three tables contain data.
+
+# 4. Contract
+- Create the executable program {{P}}REPAIR_LIST in package $TMP.
+- Selection screen:
+  - Parameter P_DATE, type DATS, mandatory: the job date to show.
+- Show the result with CL_SALV_TABLE. The output table has these columns with
+  these names: JOB_ID, CUSTOMER, MECHANIC, ITEMS, TOTAL.
+
+# 5. Business rules
+1. Include a job only if its JOB_DATE is equal to P_DATE.
+2. Include a job only if at least one item of this job is in {{P}}JOBITM.
+3. ITEMS is the number of the items of the job.
+4. TOTAL is the sum of QTY * PRICE over all items of the job.
+5. MECHANIC is the MECH_NAME of the mechanic whose MECH_ID is the MECH_ID of
+   the job.
+6. If no mechanic has this MECH_ID, MECHANIC is the text UNKNOWN.
+7. Show exactly one line for each included job.
+8. Sort the lines by TOTAL, the highest total first. If two lines have the same
+   TOTAL, sort them by JOB_ID, the lowest first.
+
+# 6. Constraints
+- Release target: SAP_BASIS 816 (ABAP Platform 2025).
+- Coding standards: Clean ABAP. Read each table with one database access.
+- Out of scope: do not change {{P}}MECH, {{P}}JOBHDR and {{P}}JOBITM.
+
+# 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.
