1. Goal

An ice cream parlour sells ice cream by the scoop. The checkout program calls one function module for each order. The function module calculates the price of the order.

2. Open questions

None.

3. Context

• Function group {{P}}FG_ICE is in package $TMP.
• Function module {{P}}ICE_SAMPLE is in this group. It is a sample module. Its interface is the interface that all modules of this group use.

4. Contract

• Create the function module {{P}}ICE_FEE in function group {{P}}FG_ICE.
• Use exactly the interface of {{P}}ICE_SAMPLE:
  • iv_flavour, importing, type string. The flavour code.
  • iv_scoops, importing, type i. The number of scoops.
  • iv_topping, importing, type string. The topping code.
  • iv_here, importing, type abap_bool. True if the customer eats the ice cream in the parlour.
  • ev_price, exporting, type decfloat34. The price of the order.
  • Exceptions: invalid_scoops, unknown_flavour, unknown_topping.

5. Business rules

1. The number of scoops must be between 1 and 5. If it is not, raise the exception INVALID_SCOOPS.
2. The flavour code gives the price of one scoop:
   • VA: 1.20
   • CH: 1.50
   • ST: 1.40 Any other flavour code raises the exception UNKNOWN_FLAVOUR.
3. The topping code gives the price of the topping:
   • NON or empty: 0.00
   • NUT: 0.60
   • SPR: 0.40 Any other topping code raises the exception UNKNOWN_TOPPING.
4. The base price is the number of scoops multiplied by the price of one scoop, plus the price of the topping.
5. If iv_here is true, add a service charge of 5 percent of the base price. If iv_here is false, there is no service charge.
6. Round the final price half up to 2 decimals. Return the result in ev_price.

6. Constraints

• Release target: 7.40 SP05. Use only ABAP syntax that exists in 7.40 SP05. Do not use syntax that was introduced later. For example, do not use common table expressions (WITH), UNION, INTERSECT or EXCEPT in Open SQL, IS INSTANCE OF, or CASE TYPE OF.
• Coding standard: Clean ABAP.
• Out of scope: do not change {{P}}ICE_SAMPLE.

7. Acceptance

• The function module is active and has no syntax error.
• The hidden tests pass.
• Write ABAP Unit tests for the function module in a global test class.
