+# 1. Goal
+A paint shop mixes custom paint colours. A customer order contains one or more
+tint components. The checkout program calls one function module for each order.
+The function module returns the total volume and the price of the mix.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The class {{P}}PAINT_MIX exists in package $TMP. It contains the public types
+  ty_tint and ty_tints. The checkout program and the function module use these
+  types.
+- The table {{P}}TINTPR exists in package $TMP. It contains the price of one
+  millilitre of each tint. The class {{P}}PAINT_MIX fills this table.
+- The function group {{P}}FG_PAINT exists in package $TMP.
+- The function module {{P}}MIX_SAMPLE exists in this function group. It is a
+  sample. It shows the interface that the checkout program uses.
+
+# 4. Contract
+- Create the function module {{P}}MIX_PRICE in function group {{P}}FG_PAINT.
+- Use exactly this interface:
+
+  IMPORTING
+    it_tints  TYPE {{P}}PAINT_MIX=>TY_TINTS
+  EXPORTING
+    ev_volume TYPE decfloat34
+    ev_price  TYPE decfloat34
+  EXCEPTIONS
+    no_components
+    invalid_quantity
+    unknown_tint
+
+- The type {{P}}PAINT_MIX=>ty_tint has these components:
+    tint_id     type c, length 4
+    quantity_ml type i
+- The type {{P}}PAINT_MIX=>ty_tints is a table of ty_tint.
+- The table {{P}}TINTPR has these fields:
+    tint_id  type c, length 4
+    price_ml type packed number, 13 digits, 3 decimals
+- The table {{P}}TINTPR contains this data:
+    WHIT 0.020
+    BLUE 0.045
+    GREY 0.030
+    GOLD 0.250
+
+# 5. Business rules
+1. The component quantity_ml is a volume in millilitres.
+2. If it_tints is empty, raise the exception NO_COMPONENTS.
+3. If a component has a quantity_ml of zero or less, raise the exception
+   INVALID_QUANTITY.
+4. If a component has a tint_id that is not in the table {{P}}TINTPR, raise the
+   exception UNKNOWN_TINT.
+5. Check rule 2 first. Then check rule 3 for all components. Then check rule 4
+   for all components. Raise only the first exception that occurs.
+6. ev_volume is the sum of the quantity_ml of all components. If the same
+   tint_id occurs more than once, all its quantities count.
+7. The material price of a component is its quantity_ml multiplied by the
+   price_ml of its tint.
+8. The mixing fee is 1.50 for each different tint_id in the order. A tint_id
+   that occurs more than once counts once.
+9. ev_price is the sum of the material prices of all components plus the mixing
+   fee. Round ev_price half up to 2 decimals.
+
+# 6. Constraints
+- Release target: 7.58 (the system runs SAP_BASIS 816).
+- Use Clean ABAP. Keep each method below 40 statements.
+- Out of scope: do not change the class {{P}}PAINT_MIX, the table {{P}}TINTPR,
+  and the function module {{P}}MIX_SAMPLE.
+
+# 7. Acceptance
+- The function module {{P}}MIX_PRICE is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests for the function module in a global test class.
