# 1. Goal
|
|
A brewery plans the bottling runs of its beer types. The planning program calls
|
|
one function module. The function module reads the open bottling orders, groups
|
|
them by beer type and stores the bottling plan.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- Function group {{P}}FG_BOT exists in package $TMP.
|
|
- The database table {{P}}BOTORD exists in package $TMP. Its fields are
|
|
client (key), order_id (key, NUMC 10), beer_type (CHAR 4) and
|
|
volume_hl (DEC 13,3).
|
|
- The database table {{P}}BOTPLN exists in package $TMP. Its fields are
|
|
client (key), beer_type (key, CHAR 4), plan_pos (INT4), total_hl (DEC 13,3)
|
|
and order_count (INT4).
|
|
|
|
# 4. Contract
|
|
Create the function module {{P}}BOT_PLAN in function group {{P}}FG_BOT.
|
|
The interface of the function module is:
|
|
- Importing parameter iv_min_hl TYPE decfloat34.
|
|
- Exporting parameter ev_total_hl TYPE decfloat34.
|
|
- Exporting parameter ev_plan_count TYPE int4.
|
|
|
|
# 5. Business rules
|
|
1. Read all rows of the table {{P}}BOTORD.
|
|
2. Ignore every order whose volume_hl is less than or equal to 0.
|
|
3. Group the other orders by beer_type. Compare beer types exactly.
|
|
4. For each group, total_hl is the sum of the volume_hl values of the orders
|
|
of the group, and order_count is the number of orders of the group.
|
|
5. Keep only the groups whose total_hl is greater than or equal to iv_min_hl.
|
|
6. Delete all rows of the table {{P}}BOTPLN and write one row per kept group.
|
|
7. The rows of {{P}}BOTPLN are numbered with plan_pos, starting at 1. The row
|
|
with the largest total_hl gets plan_pos 1. If two rows have the same
|
|
total_hl, the row with the smaller beer_type gets the smaller plan_pos.
|
|
8. ev_total_hl is the sum of the total_hl values of the kept groups. If no
|
|
group is kept, ev_total_hl is 0.
|
|
9. ev_plan_count is the number of kept groups.
|
|
10. {{P}}BOTPLN contains no rows other than the rows that rules 2 to 7 define.
|
|
|
|
# 6. Constraints
|
|
- Release target: SAP_BASIS 8.16.
|
|
- Use Clean ABAP. Keep every procedure below 40 statements.
|
|
- Out of scope: do not change the tables {{P}}BOTORD and {{P}}BOTPLN.
|
|
|
|
# 7. Acceptance
|
|
- The function module {{P}}BOT_PLAN is active and has no syntax error.
|
|
- The hidden tests pass.
|
|
- Write ABAP Unit tests for the function module in a global test class.
