Weights and Scoring Configuration

The weight and scoring configuration is a critical component of the vendor evaluation process. It determines how different performance criteria are weighted and scored to generate meaningful evaluation results.

Understanding Evaluation Criteria and Weights

S/4HANA uses three main criteria for vendor evaluation:

Quantity Evaluation
25%
Time Evaluation
25%
Price Evaluation
50%

These weights are customizable and can be adjusted based on your organization's priorities. For example, if delivery timeliness is more critical for your business, you might increase the weight for Time Evaluation.

Scoring Rules and Variance Calculations

Quantity Scoring

Variance Percentage Score Example
0% (Perfect Match) 100 Ordered: 100, Delivered: 100
-10% (Under-delivery) 65 Ordered: 10, Delivered: 9
-50% (Significant Under-delivery) 70 Ordered: 20, Delivered: 10
+5% (Over-delivery) 95 Ordered: 100, Delivered: 105

The system calculates quantity variance as: (Delivered Quantity - Ordered Quantity) / Ordered Quantity * 100

Time Scoring

Delivery Status Score Example
On Time 100 Delivered exactly on the requested delivery date
1-2 Days Late 90 Delivered 1-2 days after the requested delivery date
3-5 Days Late 70 Delivered 3-5 days after the requested delivery date
>5 Days Late 50 Delivered more than 5 days after the requested delivery date
Early Delivery 95 Delivered before the requested delivery date

The system calculates time variance based on the difference between the requested delivery date and the actual delivery date.

Price Scoring

Price Variance Percentage Score Example
0% (Perfect Match) 100 PO Price: $100, Invoice Price: $100
+1% to +3% (Small Overcharge) 90 PO Price: $100, Invoice Price: $102
+3% to +5% (Moderate Overcharge) 70 PO Price: $100, Invoice Price: $104
>+5% (Significant Overcharge) 50 PO Price: $100, Invoice Price: $106
Negative Variance (Lower Invoice Price) 100 PO Price: $100, Invoice Price: $98

The system calculates price variance as: (Invoice Price - PO Price) / PO Price * 100
