# 1. Goal
|
|
A coffee roastery plans its daily production. A planning program calls one
|
|
function module for each production day. The function module groups the roast
|
|
order lines of the day by coffee blend and returns the total green coffee
|
|
quantity of each blend. The planning program shows the blend with the largest
|
|
quantity first.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- Function group {{P}}FG_ROAST exists in package $TMP.
|
|
- Table {{P}}ROASTS exists in package $TMP. It stores the roast order lines of
|
|
a production day.
|
|
- Table {{P}}BLENDS exists in package $TMP. It is the line type of the result
|
|
table.
|
|
- The class {{P}}ROAST_SEED fills {{P}}ROASTS with sample data. Run it to get
|
|
test data.
|
|
|
|
# 4. Contract
|
|
- Create the function module {{P}}ROAST_SUM in function group {{P}}FG_ROAST.
|
|
- Interface of {{P}}ROAST_SUM:
|
|
- IMPORTING it_orders TYPE STANDARD TABLE OF {{P}}ROASTS
|
|
- EXPORTING et_totals TYPE STANDARD TABLE OF {{P}}BLENDS
|
|
- EXPORTING ev_grand_total TYPE decfloat34
|
|
- The function module has no exceptions.
|
|
|
|
# 5. Business rules
|
|
1. A line of it_orders is a production line if its quantity is greater than 0.
|
|
A line with a quantity of 0 or less is not a production line.
|
|
2. et_totals has exactly one line for each blend that has at least one
|
|
production line in it_orders.
|
|
3. The total quantity of a blend is the sum of the quantities of all its
|
|
production lines.
|
|
4. Sort et_totals by total quantity. The largest total quantity comes first.
|
|
5. If two blends have the same total quantity, the blend that is smaller in the
|
|
character order comes first.
|
|
6. ev_grand_total is the sum of the total quantities of all lines of et_totals.
|
|
7. If it_orders is empty, or if it_orders has no production line, et_totals is
|
|
empty and ev_grand_total is 0.
|
|
|
|
# 6. Constraints
|
|
- Release target: 7.58.
|
|
- Package: $TMP. Do not use transports.
|
|
- Coding standard: Clean ABAP. Keep the function module short. Choose the
|
|
internal table kind and the access path that fit the task.
|
|
- Out of scope: do not change {{P}}ROASTS, {{P}}BLENDS, {{P}}ROAST_SEED.
|
|
|
|
# 7. Acceptance
|
|
- The function module {{P}}ROAST_SUM is active and has no syntax error.
|
|
- The hidden tests pass.
|
|
- Write ABAP Unit tests for the function module in a global test class.
