+# 1. Goal
+A car dealership accepts used cars as trade-ins. A sales program calls one
+valuation for each offered car before the dealership makes an offer to the
+customer. The valuation returns the trade-in value in whole euros and a reason
+code.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The interface {{P}}IF_TRADE_IN exists in package $TMP. It is active.
+- The interface defines the whole contract of the valuation: the result
+  structure, the input types, the three brand groups, the four condition
+  grades, the reason codes and one method. Read the interface in the system.
+- The dealership uses the brand groups premium, volume and budget and the
+  condition grades A, B, C and D.
+- All amounts are whole euros. All arithmetic is integer arithmetic.
+
+# 4. Contract
+- Create the class {{P}}TRADE_IN_VALUER in package $TMP.
+- The class is public, final, and has a public constructor without parameters.
+- The class implements {{P}}IF_TRADE_IN.
+- Do not add other public methods.
+- Do not change {{P}}IF_TRADE_IN.
+
+# 5. Business rules
+Apply the rules in this sequence. Return the reason code of the first rule that
+fails. The interface defines one reason code for each rule below and one reason
+code for a successful valuation. Each code is named after the rule that it
+reports.
+1. The brand group must be one of the three brand groups that the interface
+   defines. If not, return the reason code for the brand group.
+2. The condition grade must be one of the four grades that the interface
+   defines. If not, return the reason code for the condition grade.
+3. The age in months must be between 0 and 600. If not, return the reason code
+   for the age.
+4. The mileage in kilometres must be between 0 and 1000000. If not, return the
+   reason code for the mileage.
+5. The base value is 30000 euros for the premium brand group, 20000 euros for
+   the volume brand group and 12000 euros for the budget brand group.
+6. Deduct 1 percent of the base value for each month of age.
+7. Deduct 1 percent of the base value for each complete block of 10000
+   kilometres of mileage. Only complete blocks count. A mileage of 25000
+   kilometres contains two complete blocks and 5000 kilometres that do not
+   count. A mileage of 9999 kilometres contains no complete block.
+8. Multiply the result by the grade factor: grade A 110 percent, grade B
+   100 percent, grade C 80 percent, grade D 60 percent.
+9. If the result is below 500, the value is 500.
+10. Return the value and the reason code for a successful valuation.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change {{P}}IF_TRADE_IN.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
