# 1. Goal
|
|
A purchasing department rates its suppliers. A scorecard program calls the rating
|
|
before it prints the scorecard. The program needs the weighted score and the grade
|
|
of a supplier.
|
|
|
|
# 2. Open questions
|
|
None.
|
|
|
|
# 3. Context
|
|
- All objects are in package $TMP.
|
|
- A supplier is rated in three criteria: price, quality, and delivery.
|
|
- Each criterion gets an integer rating from 1 (very poor) to 5 (very good).
|
|
- The scorecard program passes the three ratings to the class. It reads the score
|
|
and the grade from the result.
|
|
|
|
# 4. Contract
|
|
- Create the class {{P}}SUPPLIER_SCORE in package $TMP.
|
|
- The class is public, final, and has a public constructor without parameters.
|
|
- The class has these public types:
|
|
- TY_RATING: an integer type for one rating.
|
|
- TY_SCORE: a packed number with length 5 and 1 decimal place.
|
|
- TY_GRADE: a character type with length 1.
|
|
- TY_RESULT: a structure with the components SCORE (type TY_SCORE) and GRADE
|
|
(type TY_GRADE).
|
|
- The class has exactly this public method:
|
|
|
|
METHODS evaluate
|
|
IMPORTING iv_price TYPE ty_rating
|
|
iv_quality TYPE ty_rating
|
|
iv_delivery TYPE ty_rating
|
|
RETURNING VALUE(rs_result) TYPE ty_result.
|
|
|
|
- Do not add other public methods.
|
|
|
|
# 5. Business rules
|
|
Apply the rules in this sequence.
|
|
|
|
1. A rating is valid if it is an integer from 1 to 5. If at least one of the three
|
|
ratings is not valid, return score 0.0 and grade 'X'.
|
|
2. Quality is a knock-out criterion. If the quality rating is 1, return score 0.0
|
|
and grade 'X'.
|
|
3. Calculate the weighted score:
|
|
score = (price * 40 + quality * 35 + delivery * 25) / 100.
|
|
4. Round the score to one decimal place. Use commercial rounding, that is, round
|
|
half away from zero.
|
|
5. Derive the grade from the rounded score:
|
|
- 4.5 or more: 'A'
|
|
- 3.5 or more: 'B'
|
|
- 2.5 or more: 'C'
|
|
- 1.5 or more: 'D'
|
|
- less than 1.5: 'E'
|
|
|
|
# 6. Constraints
|
|
- Release target: SAP_BASIS 816.
|
|
- Coding standards: Clean ABAP. Every method has fewer than 40 statements. No
|
|
global variables. No comment that restates the code.
|
|
- Out of scope: database access, ALV, dynpro, and changes to other objects.
|
|
|
|
# 7. Acceptance
|
|
- The class is active and has no syntax error.
|
|
- The hidden tests pass.
|
|
- Write your own ABAP Unit tests for the class.
