+# 1. Goal
+A scrapyard buys scrap metal from customers. A weighing program calls one
+calculation to get the payout for a delivery. The payout has an amount and a
+reason code.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The interface {{P}}IF_SCRAP_PAYOUT exists in package $TMP. It is active.
+- The interface defines one method, the material codes, the reason codes, and the
+  structure of the result.
+- Read the interface {{P}}IF_SCRAP_PAYOUT in package $TMP. This specification does
+  not repeat the signature of the interface.
+
+# 4. Contract
+- Create the class {{P}}SCRAP_PAYOUT in package $TMP.
+- The class is public and final.
+- The class implements the interface {{P}}IF_SCRAP_PAYOUT.
+- The class has a public constructor without parameters.
+- Do not add other public methods.
+
+# 5. Business rules
+Apply the rules in this sequence. Stop at the first rule that fails.
+
+1. Convert the material code to upper case. The result must be one of the material
+   codes in the constant structure {{P}}IF_SCRAP_PAYOUT=>C_MATERIAL. If not, return
+   the reason MATERIAL and the amount 0.
+2. The weight in kilograms must be greater than 0. If not, return the reason WEIGHT
+   and the amount 0.
+3. The contamination in percent must be between 0 and 100. If not, return the reason
+   DIRTY and the amount 0.
+4. The base price per kilogram is 4.20 for copper, 1.10 for aluminium, 0.30 for
+   steel, and 3.00 for brass.
+5. The payable weight is the weight multiplied by the difference between 100 and the
+   contamination, divided by 100.
+6. The amount is the payable weight multiplied by the base price of the material.
+   Round the amount to 2 decimal places.
+7. Return the reason OK and the amount.
+
+# 6. Constraints
+- Release target: SAP_BASIS 816.
+- Coding standards: Clean ABAP. Keep every method below 40 statements. Do not use
+  global variables. Pass large parameters by reference. Do not write comments that
+  restate the code.
+- Out of scope: do not change the interface {{P}}IF_SCRAP_PAYOUT.
+
+# 7. Acceptance
+- The class {{P}}SCRAP_PAYOUT is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
