+# 1. Goal
+A tour operator checks a holiday booking before it confirms the booking. The
+booking desk calls one check method for each booking. The check method reports
+each problem as a class-based exception. Each exception carries a message and
+the values that caused the problem.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Class {{P}}CX_HOLIDAY_ERROR exists in package $TMP. It is active. It is
+  abstract and inherits from cx_static_check. It has the public read-only
+  attribute mv_message TYPE string and a public constructor with the importing
+  parameter iv_message TYPE string. The constructor sets mv_message.
+- The tour operator offers five destinations. The destination code and the
+  maximum number of travellers of each destination are:
+  ALPS 6, CRETE 4, KYOTO 8, LAPLAND 5, SAFARI 7.
+- The booking desk passes the booking and the current date to the check method.
+- A booking has a destination code, a number of travellers, a number of nights,
+  and a departure date.
+
+# 4. Contract
+Create these five classes in package $TMP. Do not change {{P}}CX_HOLIDAY_ERROR.
+
+1. Class {{P}}HOLIDAY_CHECKER
+   - The class is public and final. It has a public constructor without
+     parameters.
+   - Public type ty_dest_code, type string.
+   - Public type ty_booking, a structure with these components:
+     dest_code TYPE ty_dest_code, travellers TYPE i, nights TYPE i,
+     departure TYPE d.
+   - Public method check with this signature:
+     IMPORTING is_booking TYPE ty_booking
+               iv_today   TYPE d
+     RAISING   {{P}}CX_HOLIDAY_ERROR
+   - Do not add other public methods.
+
+2. Class {{P}}CX_UNKNOWN_DEST
+   - The class is final and inherits from {{P}}CX_HOLIDAY_ERROR.
+   - Public read-only attribute mv_dest TYPE string.
+   - Public constructor with the importing parameter iv_dest TYPE string.
+   - mv_message is 'Destination is not offered'.
+   - mv_dest holds the normalized destination code. The value has no leading or
+     trailing blanks.
+
+3. Class {{P}}CX_BAD_TRAVELLERS
+   - The class is final and inherits from {{P}}CX_HOLIDAY_ERROR.
+   - Public read-only attributes mv_travellers TYPE i and mv_max TYPE i.
+   - Public constructor with the importing parameters iv_travellers TYPE i and
+     iv_max TYPE i.
+   - mv_message is 'Number of travellers is not allowed'.
+
+4. Class {{P}}CX_BAD_NIGHTS
+   - The class is final and inherits from {{P}}CX_HOLIDAY_ERROR.
+   - Public read-only attribute mv_nights TYPE i.
+   - Public constructor with the importing parameter iv_nights TYPE i.
+   - mv_message is 'Number of nights is not allowed'.
+
+5. Class {{P}}CX_BAD_DEPARTURE
+   - The class is final and inherits from {{P}}CX_HOLIDAY_ERROR.
+   - Public read-only attributes mv_departure TYPE d and mv_earliest TYPE d.
+   - Public constructor with the importing parameters iv_departure TYPE d and
+     iv_earliest TYPE d.
+   - mv_message is 'Departure date is too early'.
+
+# 5. Business rules
+The method check applies these rules in this sequence. The method raises the
+exception of the first rule that fails. If no rule fails, the method returns
+without an exception.
+
+1. Normalize the destination code: remove all spaces and convert all letters to
+   upper case.
+2. The normalized code must be ALPS, CRETE, KYOTO, LAPLAND, or SAFARI. If it is
+   not, raise {{P}}CX_UNKNOWN_DEST. Pass the normalized code in iv_dest.
+3. The number of travellers must be 1 or more. It must not be more than the
+   maximum number of travellers of the destination. If a value is not correct,
+   raise {{P}}CX_BAD_TRAVELLERS. Pass the number of travellers in iv_travellers
+   and the maximum of the destination in iv_max.
+4. The number of nights must be 2 or more. It must not be more than 28. If a
+   value is not correct, raise {{P}}CX_BAD_NIGHTS. Pass the number of nights in
+   iv_nights.
+5. The departure date must be at least 14 days after iv_today. If it is not,
+   raise {{P}}CX_BAD_DEPARTURE. Pass the departure date in iv_departure and the
+   earliest possible date (iv_today plus 14 days) in iv_earliest.
+
+# 6. Constraints
+- Release target: SAP_BASIS 816 (ABAP Platform 2025).
+- Coding standards: Clean ABAP. Methods below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change {{P}}CX_HOLIDAY_ERROR. Do not create a database
+  table, a CDS view entity, a function module, or a report. Do not change the
+  signature of check.
+
+# 7. Acceptance
+- All five classes are active and have no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for {{P}}HOLIDAY_CHECKER.
