+# 1. Goal
+A golf club prices a tee time booking. The pro shop calls one function module
+for each booking before it confirms the booking. The function module rejects an
+invalid booking with a class-based exception and returns the green fee of a
+valid booking.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Function group {{P}}FG_GOLF exists in package $TMP.
+- The club sells rounds of 9 holes and rounds of 18 holes.
+- The club has three player categories: members, guests and juniors.
+- The pro shop calls the function module for each booking.
+
+# 4. Contract
+Exception class {{P}}CX_GOLF in package $TMP:
+- The class is public, final and inherits from CX_STATIC_CHECK.
+- The class has a public constructor with the importing parameters iv_reason
+  (type string) and iv_message (type string).
+- The class has the public read-only attributes mv_reason (type string) and
+  mv_message (type string).
+- The constructor stores iv_reason in mv_reason and iv_message in mv_message.
+
+Function module {{P}}GOLF_FEE in function group {{P}}FG_GOLF:
+- Importing parameters:
+  - iv_category type string
+  - iv_holes type i
+  - iv_players type i
+  - iv_tee_hour type i
+- Exporting parameter:
+  - ev_fee type decfloat34
+- The function module raises the class-based exception {{P}}CX_GOLF. Declare
+  this exception in the interface of the function module, because the caller
+  handles it with CATCH {{P}}CX_GOLF.
+- The function module has no classic exceptions.
+
+# 5. Business rules
+1. The number of players must be between 1 and 4. If it is not, raise
+   {{P}}CX_GOLF with the reason INVALID_PLAYERS and the message
+   "Number of players must be between 1 and 4".
+2. The number of holes must be 9 or 18. If it is not, raise {{P}}CX_GOLF with
+   the reason INVALID_HOLES and the message "Number of holes must be 9 or 18".
+3. The player category must be M (member), G (guest) or J (junior). If it is
+   not, raise {{P}}CX_GOLF with the reason INVALID_CATEGORY and the message
+   "Player category must be M, G or J".
+4. The tee hour must be between 6 and 20. If it is not, raise {{P}}CX_GOLF with
+   the reason INVALID_TEE_HOUR and the message "Tee hour must be between 6 and
+   20".
+5. Check the rules 1 to 4 in this order. Raise only the first exception that
+   applies.
+6. The green fee per player for 18 holes is 25.00 for a member, 62.50 for a
+   guest and 12.50 for a junior. For 9 holes the green fee per player is half
+   of the green fee per player for 18 holes.
+7. Twilight rate: if the tee hour is 18 or later, reduce the green fee per
+   player by 25 %. Round the result half up to 2 decimals.
+8. The total fee is the green fee per player times the number of players.
+9. Group discount: if the booking has 4 players, reduce the total fee by 10 %.
+   Round the result half up to 2 decimals. Apply this discount after the
+   twilight rate.
+10. If the booking is valid, return the total fee in ev_fee and raise no
+    exception.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP. Keep every method below 40 statements.
+- Out of scope: none.
+
+# 7. Acceptance
+- The exception class and the function module are active and have no syntax
+  error.
+- The hidden tests pass.
+- Write ABAP Unit tests for the function module in a global test class.
