+# 1. Goal
+Check a work booking of a production shift and calculate the pay of the shift. A
+payroll program calls the check before it posts the pay. The program needs one
+reason code for each booking that is not correct.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The class {{P}}SHIFT_BOOKER does not exist. You create it.
+- The exception class {{P}}CX_SHIFT_ERROR does not exist. You create it.
+- The business uses the words hours, mode, order, date, count, group and value.
+  These words are reserved words or SQL words. The contract below uses other
+  names for the same concepts.
+
+# 4. Contract
+## 4.1 Exception class {{P}}CX_SHIFT_ERROR
+- The class is in package $TMP. It inherits from CX_STATIC_CHECK.
+- The class has the public instance attribute MV_REASON. The type is CHAR 10.
+  MV_REASON holds the reason code of the error.
+- Do not add other public components.
+
+## 4.2 Class {{P}}SHIFT_BOOKER
+- The class is in package $TMP. It is public, final, and has a public constructor
+  without parameters.
+- Public types:
+  - TY_AMOUNT: packed number, length 9, 2 decimal places.
+  - TY_HOURS: packed number, length 5, 2 decimal places.
+  - TY_MODE: CHAR 3.
+  - TY_GROUP: CHAR 1.
+  - TY_ORDER: CHAR 10.
+  - TY_SHIFT: structure with these components:
+    - ORDER_NO: TYPE TY_ORDER
+    - START_DATE: TYPE d
+    - WORK_HOURS: TYPE TY_HOURS
+    - CALC_MODE: TYPE TY_MODE
+    - GROUP_CODE: TYPE TY_GROUP
+    - PIECE_COUNT: TYPE i
+- Public method:
+  EVALUATE
+    IMPORTING is_shift TYPE ty_shift
+    RETURNING VALUE(rv_pay) TYPE ty_amount
+    RAISING {{P}}CX_SHIFT_ERROR
+- Do not add other public methods.
+
+# 5. Business rules
+The method EVALUATE checks the booking. Apply the rules in this sequence. The
+method raises {{P}}CX_SHIFT_ERROR with the reason code of the first rule that
+fails.
+1. If ORDER_NO is empty, the reason code is ORDER.
+2. If START_DATE is initial, the reason code is DATE.
+3. If WORK_HOURS is not greater than zero, the reason code is HOURS.
+4. CALC_MODE must be STD, OT1 or OT2. If not, the reason code is MODE.
+5. GROUP_CODE must be A, B or C. If not, the reason code is GROUP.
+6. If PIECE_COUNT is less than 1, the reason code is COUNT.
+If all rules pass, the method returns the value of the shift.
+
+The value of the shift is:
+  WORK_HOURS x base rate x mode factor + PIECE_COUNT x 0.50
+- The base rate of the group is: A = 18.00, B = 22.00, C = 26.00.
+- The mode factor is: STD = 1.0, OT1 = 1.5, OT2 = 2.0.
+- The value has 2 decimal places.
+
+# 6. Constraints
+- Release target: SAP_BASIS 816 (ABAP Platform 2025).
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Do not use the words HOURS, MODE, ORDER, DATE, COUNT, GROUP or VALUE as the name
+  of a field, of a component or of a parameter. The reason codes in the rules
+  above are values, not names.
+- Out of scope: do not create other objects. Do not use transports.
+
+# 7. Acceptance
+- The two classes are active and have no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for {{P}}SHIFT_BOOKER.
