+# 1. Goal
+Calculate the internal price of a print job for the print shop of a company. A
+billing program calls the calculation before it charges the cost centre of a
+department. Invalid job data must raise a class-based exception.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Package $TMP. No other object exists for this topic.
+- The billing program catches the exceptions and shows the reason to the user.
+  The names of the classes and their public components are fixed.
+
+# 4. Contract
+Create three classes in package $TMP.
+
+## {{P}}CX_PRINT_JOB_ERROR
+- Public, final, inherits from CX_ROOT.
+- Public type TY_REASON, character 10.
+- Public constant structure C_REASON with the components PAGES, COPIES, PAPER,
+  COLOR and DEPT. The values are 'PAGES', 'COPIES', 'PAPER', 'COLOR' and
+  'DEPT'.
+- Public attribute MV_REASON of type TY_REASON.
+- Public constructor with the importing parameter IV_REASON of type TY_REASON.
+  The constructor writes IV_REASON to MV_REASON.
+
+## {{P}}CX_PRINT_LIMIT
+- Public, final, inherits from CX_ROOT.
+- Public attribute MV_PAGES of type I.
+- Public constructor with the importing parameter IV_PAGES of type I. The
+  constructor writes IV_PAGES to MV_PAGES.
+
+## {{P}}PRINT_JOB_PRICER
+- Public, final, public constructor without parameters.
+- Public types: TY_PAPER (character 4), TY_COLOR (character 1), TY_DEPT
+  (character 4), TY_PRICE (packed number, length 8, 2 decimals).
+- Public method CALCULATE_PRICE with these parameters:
+  - IMPORTING IV_PAGES TYPE I
+  - IMPORTING IV_COPIES TYPE I
+  - IMPORTING IV_PAPER TYPE TY_PAPER
+  - IMPORTING IV_COLOR TYPE TY_COLOR
+  - IMPORTING IV_DEPT TYPE TY_DEPT
+  - RETURNING VALUE(RV_PRICE) TYPE TY_PRICE
+  - RAISING {{P}}CX_PRINT_JOB_ERROR and {{P}}CX_PRINT_LIMIT
+- Do not add other public methods.
+
+# 5. Business rules
+Apply the rules in this sequence.
+
+1. Check the input in this order. Raise the exception of the first rule that
+   fails.
+   1. IV_PAGES is smaller than 1: raise {{P}}CX_PRINT_JOB_ERROR with the
+      reason PAGES.
+   2. IV_COPIES is smaller than 1: raise {{P}}CX_PRINT_JOB_ERROR with the
+      reason COPIES.
+   3. IV_PAPER is not 'A4', 'A3' or 'A5': raise {{P}}CX_PRINT_JOB_ERROR with
+      the reason PAPER.
+   4. IV_COLOR is not 'C' or 'M': raise {{P}}CX_PRINT_JOB_ERROR with the
+      reason COLOR.
+   5. IV_DEPT is not 'SALE', 'HR', 'IT' or 'PROD': raise
+      {{P}}CX_PRINT_JOB_ERROR with the reason DEPT.
+2. The total number of pages is IV_PAGES multiplied by IV_COPIES.
+3. If the total number of pages is greater than 5000, raise
+   {{P}}CX_PRINT_LIMIT with MV_PAGES equal to the total number of pages.
+4. The price of one page is 0.03 for A5, 0.05 for A4 and 0.09 for A3. For the
+   color mode 'C', multiply the price of one page by 4.
+5. The gross price is the total number of pages multiplied by the price of one
+   page.
+6. Volume discount on the gross price: 10 per cent if the total number of
+   pages is 1000 or more, 5 per cent if the total number of pages is 500 or
+   more, otherwise no discount.
+7. The net price is the gross price minus the discount.
+8. If the net price is smaller than 1.00, the price is 1.00 (minimum charge).
+9. Return the price.
+
+# 6. Constraints
+- Release target: SAP_BASIS 8.16.
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: no database table, no report, no function module, no CDS view.
+
+# 7. Acceptance
+- The three classes are active and have no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for {{P}}PRINT_JOB_PRICER.
