# 1. Goal
|
|
A warehouse planner checks if the free stock covers the requirements of a
|
|
production run. The planner sends a list of stock items and a list of
|
|
requirements to a class. The class returns one result row for each requirement.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- The interface {{P}}IF_STOCK_COVER exists in package $TMP. It is active.
|
|
- The interface contains the types TY_MATERIAL (CHAR 18), TY_PLANT (CHAR 4),
|
|
TY_QUANTITY (PACKED 13, 3) and TY_STATUS (CHAR 10).
|
|
- The interface contains the structures TY_STOCK_ITEM, TY_REQUIREMENT and
|
|
TY_RESULT and the table types TT_STOCK_ITEM, TT_REQUIREMENT and TT_RESULT.
|
|
- The interface contains the constant structure C_STATUS with the values OK,
|
|
SHORT and INVALID.
|
|
- The interface has the method CHECK. It imports a stock table and a requirement
|
|
table and returns a result table.
|
|
- The interface has the method SHORTAGES. It imports a result table and returns a
|
|
result table.
|
|
|
|
# 4. Contract
|
|
- Create the class {{P}}STOCK_COVER_CHECKER in package $TMP.
|
|
- The class is public and final.
|
|
- The class implements {{P}}IF_STOCK_COVER.
|
|
- Do not add other public methods.
|
|
- The hidden tests create the class with NEW {{P}}STOCK_COVER_CHECKER( ).
|
|

# 5. Business rules
|
|
|
|
## Stock
|
|
1. Each stock item has a material, a plant and a quantity. Ignore every stock
|
|
item whose quantity is less than zero.
|
|
2. Sum the quantities of the remaining stock items for each combination of
|
|
material and plant. This sum is the free stock of the material and plant.
|
|
3. Compare material and plant without regard to case. Remove all blanks before
|
|
you compare them.
|
|
|
|
## Requirements
|
|
4. Process the requirements in the given sequence. The result contains one row
|
|
for each requirement in the same sequence.
|
|
5. The available quantity of a requirement is the free stock of its material and
|
|
plant at the time of the requirement. If no stock exists for the material and
|
|
plant, the available quantity is 0.
|
|
6. If the required quantity is less than or equal to 0, the status is INVALID.
|
|
The requirement does not use free stock. The shortage is 0.
|
|
7. Else if the available quantity is greater than or equal to the required
|
|
quantity, the status is OK. The shortage is 0. The requirement uses the
|
|
required quantity of the free stock.
|
|
8. Else the status is SHORT. The requirement uses all free stock. The shortage is
|
|
the required quantity minus the available quantity.
|
|
|
|
## Result
|
|
9. A result row contains the material and the plant of the requirement without a
|
|
change, the required quantity, the available quantity, the shortage and the
|
|
status.
|
|
10. The method SHORTAGES returns all rows of the result table whose status is
|
|
SHORT. Sort these rows by material in ascending order and then by plant in
|
|
ascending order. The result can be empty.
|
|
|
|
# 6. Constraints
|
|
- Release target: 8.16 (SAP_BASIS 816).
|
|
- 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_STOCK_COVER.
|
|
|
|
# 7. Acceptance
|
|
- The class is active and has no syntax error.
|
|
- The hidden tests pass.
|
|
- Write your own ABAP Unit tests for the class.
