1. Goal

Calculate the discount percentage for a wholesale order. A sales program calls the calculation before it prices the order. The program needs one discount percentage for each order.

2. Open questions

None.

3. Context

• The interface {{P}}IF_DISCOUNT exists in package $TMP. It is active.
• The interface has the type TY_GROUP (CHAR 1), the type TY_PERCENT (P length 5 with 2 decimals), the constants C_GROUP_KEY ('A') and C_GROUP_STANDARD ('S'), and one method: CALCULATE IMPORTING iv_quantity TYPE i iv_group TYPE ty_group RETURNING VALUE(rv_percent) TYPE ty_percent.

4. Contract

• Create the class {{P}}VOLUME_DISCOUNT in package $TMP.
• The class is public, final, and has a public constructor without parameters.
• The class implements {{P}}IF_DISCOUNT.
• Do not add other public methods.

5. Business rules

The discount percentage is the sum of the customer discount and the volume discount. The result is at most 12.00.

1. Customer discount:
   • Group C_GROUP_KEY: 6.00.
   • Group C_GROUP_STANDARD: 0.00.
   • Any other group: 0.00.
2. Volume discount. The order quantity is the number of pieces:
   • Less than 100 pieces: 0.00.
   • More than 100 pieces and less than 500 pieces: 3.00.
   • 500 pieces or more: 7.00.
3. Add the customer discount and the volume discount. If the sum is more than 12.00, the result is 12.00.

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_DISCOUNT.
• If a business rule is missing or two business rules contradict, do not create the object. Report the gap.

7. Acceptance

• The class is active and has no syntax error.
• Write your own ABAP Unit tests for the class.
