Calculating Scores for Automatic Subcriteria: Overview 
Calculating Scores for Automatic Subcriteria: Overview
Use
This section explains how the Vendor Evaluation system calculates the scores for automatic subcriteria.
For each automatic subcriterion in the SAP Standard System there is a specific pre-defined scoring method.
These methods cannot be changed by the user.
This section outlines the methods for the following subcriteria:
Subcriterion |
Main criterion |
Price level Price history |
Price |
Goods receipt Quality audit Complaints/rejection level |
Quality |
On-time delivery performance Quantity reliability Compliance with shipping instructions Adherence to confirmation date |
Delivery |
Prerequisites
This section provides you with additional information on how the system calculates scores.
Parameters in Customizing
When the system calculates the scores for automatic subcriteria, it uses the control parameters defined in Customizing. Check that all the parameters are correctly maintained.
Validity Period of Data
When calculating scores, the system only includes data whose dates lie within the validity period defined in Customizing (for example, a period of 150 days extending from the current date back into the past).
Updating and Calculating
From the time of the last evaluation, the system continues to record scores for the automatic subcriteria for the main criterion "Quality" (Goods Receipt, Quality Audit and Complaints/Rejection Level) and the main criterion "Delivery" (On-Time Delivery Performance, Quantity Reliability, Compliance with Shipping Instructions, and Adherence to Confirmation Date).
The score for the main criterion "Quality" is updated when inspection lot results are entered in the SAP Quality Management module. Quality is checked either at the time of goods receipt (subcriterion "Goods Receipt"), during the quality audit at the vendor’s site (subcriterion "Quality Audit"), or during production when a quality notification is entered (subcriterion "Complaints/Rejection Level").
The score for the main criterion "Delivery" is updated when goods are received against purchase orders. A new individual score is calculated after each goods receipt. This is then included in the previous score with the application of a smoothing factor.
Updating is only carried out at statistical level. That is to say, the scores of the last evaluation are not automatically updated. If you display the last evaluation, this will still show the "old" scores. You will not see the current scores until you carry out a re-evaluation.
Each time you run a new evaluation, the system calculates the average score for all the materials you have procured from the vendor.
The result of the calculation is the vendor's score for the relevant subcriterion.
