+# 1. Goal
+A quarry sells gravel to building companies. A sales program calls the price
+calculation for each order. Calculate the net amount of one gravel order.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The table {{P}}GRV_ORD exists in package $TMP. It contains the gravel orders.
+  The columns are:
+  - ORDER_ID (CHAR 10): the order number.
+  - GRADE (CHAR 1): the gravel grade.
+  - TONNES (INT4): the order quantity in whole tonnes.
+  - CUSTOMER (CHAR 30): the name of the customer.
+- The seed class {{P}}SEED_GRV fills the table with test data.
+
+# 4. Contract
+- Create the class {{P}}GRAVEL_PRICER in package $TMP.
+- The class is public, final, and has a public constructor without parameters.
+- Define these public types:
+  - TY_ORDER_ID TYPE c LENGTH 10.
+  - TY_GRADE TYPE c LENGTH 1.
+  - TY_TONNES TYPE i.
+  - TY_AMOUNT TYPE p LENGTH 8 DECIMALS 2.
+  - TY_REASON TYPE c LENGTH 10.
+  - TY_RESULT: a structure with the components NET_AMOUNT (TYPE ty_amount) and
+    REASON (TYPE ty_reason).
+- Define the public constant structure C_REASON with these components of type
+  TY_REASON: OK, NOT_FOUND, GRADE, QUANTITY.
+- Define one public method:
+  PRICE_ORDER
+    IMPORTING iv_order_id TYPE ty_order_id
+    RETURNING VALUE(rs_result) TYPE ty_result.
+- Do not add other public methods.
+
+# 5. Business rules
+Apply the rules in this sequence. Return the reason of the first rule that fails.
+1. Read the order with the number iv_order_id from the table {{P}}GRV_ORD. If
+   the table has no order with this number, return NOT_FOUND.
+2. The grade must be F (fine), M (medium) or C (coarse). If the grade is not
+   one of these three letters, return GRADE.
+3. The quantity must be greater than zero. If the quantity is zero or negative,
+   return QUANTITY.
+4. The base price of one tonne is 42.00 EUR for grade F, 36.00 EUR for grade M
+   and 30.00 EUR for grade C.
+5. The discount depends on the order quantity:
+   - An order of up to 4 tonnes gets no discount.
+   - An order of 6 to 19 tonnes gets a discount of 5 percent.
+   - An order of 20 tonnes or more gets a discount of 10 percent.
+6. The net amount is the base price multiplied by the quantity, less the
+   discount. Round the net amount to 2 decimals. Return OK.
+
+# 6. Constraints
+- Release target: SAP_BASIS 816.
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change the table {{P}}GRV_ORD and the seed class
+  {{P}}SEED_GRV.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
