 # 1. Goal
-
-A bike-sharing operator moves bikes between its stations. A background job
-calls one function module to apply the planned moves of the operator. The
-function module reads the planned moves and the current state of the stations
-from the database, applies the moves, and writes the new state of the stations
-back to the database. The function module returns the number of applied moves
-and the number of rejected moves.
+A rail infrastructure manager charges a track access fee to train operating
+companies. A billing program calls one function module for each operating day.
+The function module calculates the fee of each train path and groups the result
+by train category.
 
 # 2. Open questions
-
 None.
 
 # 3. Context
-
-- Function group {{P}}FG_BIKE exists in package $TMP.
-- Table {{P}}STATION exists in package $TMP. It holds the current state of the
-  stations of the operator. The table is client-dependent.
-- Table {{P}}MOVE exists in package $TMP. It holds the planned moves. The table
-  is client-dependent.
-- The station IDs in {{P}}STATION are unique. The move numbers in {{P}}MOVE are
-  unique.
-- The function module reads and changes the two tables. It works on the data of
-  the current client.
+- Function group {{P}}FG_TRACK exists in package $TMP.
+- Function module {{P}}TRACK_SAMPLE exists in this group. It shows the interface
+  that the billing program uses. Do not change it.
+- The global class {{P}}TRACK_TYPES exists in package $TMP. It only holds the row
+  types of the input and of the result. Do not change it. Its public types are:
+  - TY_PATH: PATH_ID (type N, length 8), TRAIN_CAT (type C, length 2),
+    DISTANCE_KM (packed, length 13, 2 decimals), NIGHT_FLAG (type C, length 1).
+  - TT_PATH: standard table of TY_PATH.
+  - TY_FEE: TRAIN_CAT (type C, length 2), PATH_COUNT (type I), TOTAL_KM (packed,
+    length 13, 2 decimals), TOTAL_FEE (packed, length 13, 2 decimals).
+  - TT_FEE: standard table of TY_FEE.
+- The billing program builds a standard table with the components of TY_PATH and
+  reads a standard table with the components of TY_FEE. The component names are
+  the interface between the billing program and the function module.
 
 # 4. Contract
-
-Function module {{P}}BIKE_REBALANCE in the function group {{P}}FG_BIKE:
-
-IMPORTING
-  iv_dry_run TYPE abap_bool
-EXPORTING
-  ev_applied TYPE i
-  ev_rejected TYPE i
-
-Table {{P}}STATION:
-
-  client       (key)
-  station_id   (key) TYPE c LENGTH 6
-  station_name       TYPE c LENGTH 30
-  capacity           TYPE i
-  bikes              TYPE i
-
-Table {{P}}MOVE:
-
-  client    (key)
-  move_no   (key) TYPE i
-  source_id       TYPE c LENGTH 6
-  target_id       TYPE c LENGTH 6
-  quantity        TYPE i
+Create the function module {{P}}TRACK_FEE in function group {{P}}FG_TRACK with
+this interface:
+- Importing parameter IT_PATHS, type STANDARD TABLE.
+- Exporting parameter ET_FEES, type STANDARD TABLE.
+- Exceptions INVALID_DISTANCE and INVALID_CATEGORY.
+The two table parameters are generic standard tables. Their row components are
+fixed by TY_PATH and TY_FEE of {{P}}TRACK_TYPES.
 
 # 5. Business rules
-
-1. Read all rows of {{P}}STATION and all rows of {{P}}MOVE.
-2. Apply the moves in ascending order of move_no. Do not apply them in the
-   order of the table.
-3. A move is rejected if at least one of these conditions is true:
-   - quantity is less than or equal to 0;
-   - source_id and target_id are equal;
-   - source_id is not the ID of a station in {{P}}STATION;
-   - target_id is not the ID of a station in {{P}}STATION;
-   - the source station has fewer bikes than quantity;
-   - the target station has fewer free docks than quantity. The free docks of
-     a station are capacity minus bikes.
-4. A rejected move does not change any station.
-5. An accepted move subtracts quantity from the bikes of the source station
-   and adds quantity to the bikes of the target station.
-6. After the last move, the function module writes the new bikes value of the
-   stations back to {{P}}STATION. station_name and capacity do not change.
-7. If iv_dry_run is true, the function module does not change {{P}}STATION.
-8. ev_applied is the number of accepted moves. ev_rejected is the number of
-   rejected moves. Both numbers are also returned if iv_dry_run is true.
+1. A train path with DISTANCE_KM less than or equal to zero is not valid. Raise
+   the exception INVALID_DISTANCE.
+2. The rate of a train category is:
+   - IC: 1.20 per kilometre
+   - RG: 0.90 per kilometre
+   - FR: 0.60 per kilometre
+   - SP: 1.50 per kilometre
+3. A train category that is not in rule 2 is not valid. Raise the exception
+   INVALID_CATEGORY.
+4. The fee of one path is DISTANCE_KM multiplied by the rate of its train
+   category.
+5. If NIGHT_FLAG is 'X', multiply the fee of the path by 1.20.
+6. Round the fee of the path half up to two decimals.
+7. The minimum fee of one path is 5.00. If the fee of the path is less than
+   5.00, use 5.00.
+8. The result table has one row for each train category that occurs in the
+   input table.
+9. PATH_COUNT is the number of paths of the category.
+10. TOTAL_KM is the sum of DISTANCE_KM of the paths of the category.
+11. TOTAL_FEE is the sum of the fees of the paths of the category.
+12. Sort the result table in ascending order of TRAIN_CAT.
+13. If the input table is empty, the result table is empty. Do not raise an
+    exception.
 
 # 6. Constraints
-
-- Release target: SAP_BASIS 816 (ABAP Platform 2025).
-- Package: $TMP. Do not create a transport request.
-- Clean ABAP. Keep the function module and every method below 40 statements.
-- Out of scope: do not change {{P}}STATION, {{P}}MOVE and {{P}}SEED_BIKE.
+- Release target: 8.16.
+- Coding standard: Clean ABAP. Keep methods below 40 statements. Pass large
+  parameters by reference.
+- Out of scope: do not change {{P}}TRACK_SAMPLE or {{P}}TRACK_TYPES.
 
 # 7. Acceptance
-
 - The function module is active and has no syntax error.
 - The hidden tests pass.
 - Write ABAP Unit tests for the function module in a global test class.
