Vendor Evaluation Smoothing Factor an average

Hi,
We are setting up Vendor Evaluation and would like the Delivery scores to be closer to a true average of all of the scores. We are having difficulty getting to that number. Is there a way to do it in SAP?
Thanks.

Config Smoothing factor in vendor evaluation

Dear MM experts,
Please let me know where I can config smoothing factor of score in vendor evaluation!
Thanks!

Hi,
what do you mean by smoothing factor. Normally the primary criteria used for vendor evaluation is
1. Price
2. Quality
3. Delivery norms
4. Service
based on 4 above points the evaluation is reveiwed.

Smoothing factor in Vendor evaluation

Hi,
I'm not able to understand the math underneath the "smoothing factor" used in vendor evaluation. Could someone throw some light in this?
thanks!

Hi
A score for a new goods receipt or the scores for a new service will change the existing scores for the current month.
The new individual score does not have the same significance as the previous composite score, because the latter was calculated from a number of individual scores. For this reason, the new individual score is given a lower weighting (that is to say, it is smoothed).
In carrying out this process, the system applies the relevant smoothing factors that you have defined for each individual score in Customising.
OMGL is the transaction to configure smoothing factor.
hope it helps.

Smoothing factors for Vendor Evaluation for Services

Hi Team,
How to apply smoothing factors for Quality and Timeliness of services in External Services. Any help is appreciated.
Thanks
ANita.

Hi ,
I will try to explain with one example
Actually in vendor evaluation , we are going to get only one percentage say for a material A for example Qty reliability - smoothing factor is 0.20
Material A is ordered by so many purchase orders and many goods receipts are done in many times. Goods receipt is done 6 times till now and the score is 80% . Now GR is done for 7th time . If the qty reliability is 100 % for this GR
the score is calculated in the following way
80%0.8+100%0.2 --- this the score after the 7th goods receipt....
Hope now u understand .... If u still have queries please post your feedback...
If u are satisfied , please reward points

Average variance in ranking list of vendor evaluation

Dear Gurus,
When we run the ranking list for vendor evaluation for a purchase org, in the last column there is a score for average variance for each of the vendor. COuld anyone tell me the significance of the same.
Also is there any better way to get the list in tabular form/ ALV grid format.
Thanks a ton
Kamal

I am interested in this also. Need to trigger Evaluation survey being sent out when GR is posted.

Delivery rating in vendor evaluation

Can I know on what logic system calculates the delivery rating, for schedule agreement which has more than one schedule lines.
Regards,
M.M

Dear Magesh,
This is for On time delivery:
===========================================================
At the time of a goods receipt against a purchase order, the system checks whether the delivery was on time or late:
GR date - delivery date = date variance
If the delivery was on time, the system checks whether a minimum delivery quantity is to be taken into account.
It checks the Minimum delivery quantity/standardizing value for delivery time variance from material indicator.
If the indicator has been selected, it checks whether a value has been maintained in the material master record.
If a value exists, it is used. If no value exists, the value from the Minimum delivery percentage field is used. If there no such value in this case either, goods receipts of fractions of the order quantity are included in the calculation of the score.
If the indicator has not been selected, the value from the Minimum delivery percentage field is used. If no value exists, goods receipts of fractions of the order quantity are included in the calculation of the score.
If the minimum delivery quantity is not reached, the system does not determine a score for the goods receipt.
If the minimum delivery quantity is reached and the delivery date adhered to, the variance is zero and the system awards the highest points score for the relevant goods receipt.
If the delivery is not on time, the system calculates the date variance in days and converts it into a percentage variance.
In the process, the system searches for the standardizing value as follows:
It checks the Minimum delivery quantity/standardizing value for delivery time variance from material indicator.
If the indicator has been selected, it checks whether a value has been maintained in the material master record.
If a value exists, it is used. If not, the value from the Standardizing value for delivery time variance field is used. If there is no such value in this case either, one of the following values is used:
in the case of goods receipts against scheduling agreement releases: the firm zone
in the case of goods receipts against purchase orders: the difference between the statistical delivery date and the order date
If the indicator has not been selected, the value from the Standardizing value for delivery time variance field is used. If there is no such value, one of the following values is used
in the case of goods receipts against scheduling agreement releases: the firm zone
in the case of goods receipts against purchase orders: the difference between the statistical delivery date and the order date
The system then awards the score you defined in Customizing for this percentage variance.
The new score is then included in the vendor's previous score for the subcriterion. To calculate the new score for the subcriterion from the already existing composite score and this new individual score, the system applies the smoothing factor Date variance defined in Customizing.
When you run a new evaluation, the system calculates the average of the individual scores for all materials. The result is the vendor's score for "On-Time Delivery Performance".
If a goods receipt covers several schedule lines, MM Vendor Evaluation performs this calculation for each schedule line.
This results in more than one score for the single goods receipt. Each of these scores is multiplied by the quantity delivered against the relevant schedule line and is thus weighted by quantity.
The sum of the weighted points scores is divided by the total goods receipt quantity. The result is the score for this one goods receipt.
The score for the goods receipt is smoothed and included in the existing score for on-time delivery performance for the vendor
Adherence to Conf. Date :
===========================================================
1. When a goods receipt is posted for an order item, the system checks whether open inbound deliveries exist for the order item, i.e. inbound deliveries for which no goods receipts have yet been recorded.
If open inbound deliveries exist, the system checks whether the date previously notified by the vendor has been adhered to or whether the goods receipt date differs from the date thus confirmed:
GR date - date confirmed by vendor in shipping notification = date variance
2. If the delivery was on time, the system checks whether a minimum delivery quantity has been defined in Customizing.
a. If you have not set a minimum delivery quantity, goods receipts representing partial deliveries will also be included in the calculation of the score.
b. If the minimum delivery quantity is not reached, the system does not determine a score for the goods receipt.
c. If the minimum delivery quantity is reached and the delivery is on time, the variance is zero. This means that the system awards the maximum score for the goods receipt.
3. If the delivery date is not in accordance with the notified one, the system calculates the date variance in days and converts it into a percentage variance.
4. The system then awards the score you defined in Customizing for this percentage variance.
5. The new score is then merged with the vendor's previous score for the subcriterion. To calculate the new score for the subcriterion from the already existing composite score and this new individual score, the system applies the smoothing factor On-time delivery performance/Timeliness of service provision (defined in Customizing for Vendor Evaluation under Purchasing organization data for Vendor Evaluation).
6. When you run a new evaluation, the system calculates the average of the individual scores for all materials. The result is the vendors score for adherence to the confirmation date.
If a goods receipt covers several schedule lines, MM Vendor Evaluation performs this calculation for each schedule line.
This results in more than one score for the single goods receipt. Each of these scores is multiplied by the quantity delivered against the relevant schedule line and is thus weighted by quantity.
The sum of the weighted points scores is divided by the total goods receipt quantity. The result is the score for this one goods receipt.
The score for the goods receipt is smoothed and merged with the existing score for adherence to the confirmation date for the vendor.

Goods receipt sub critaria in vendor evaluation

In vendor evaluation there is one sub-critaria goods receipt under main critaria quality, in this how system calcutae the tax.
i went through the sap help doc, in this it is mentiaoned that
"When you run an automatic re-evaluation for a vendor, the system selects all the incoming inspection lots for the vendor that lie within the validity period and calculates the average of the scores. The result is the vendor's score for the quality of goods received."
i m not understand with this. plz specify in your words and where we maintain the validity period?

Hi,
In the sub-criteria Goods Receipt, system dows not calculate tax. In the main criteria of Quality, if your material is maintained for quality inspection type 01, then system creates inspection lots for GRN. The score of each inspection lot is calculated based on you settings (For example based on usage decision). The system then saves these scores of each inspection lot. These scores are then averaged out for all the inspection lots those lie within the validity periods.
Hope this helps,
Regards,
Prashant

Vendor Evaluation in Background

Dear Gurus,
For vendor evaluation in Back ground, Do i need to maintain weight keys? then where can i see the output report once after running vendor evaluation in background.
Please advice
Thanks
RS

Dear,
Weighting Key is an identifier under which weighting factors for a number of main criteria can be grouped together and saved. If you know that you want to carry out an evaluation with certain main criteria and certain weighting factors, you can save this combination under a weighting key.
When you carry out the next vendor evaluation, just enter the relevant weighting key instead of entering a weighting factor for each individual criterion. The stardard two keys available are 01, 02.
If you do not have the weighting key, use the possible entries facility.
Next, in the background processing, usually evaluate vendors belonging to the same group (that is, vendors who have the weighting key). However, it is possible that you have selected an interval that contains different groups of vendors. For this reason, you may not enter a Weighting Key.
However the evaluation with weighting keys are preferred (basing on your organizations requirements and client performance, these may not be required). If you have enough time and interested to review the subject please have a look at: http://help.sap.com/printdocu/core/Print46c/EN/data/pdf/MMISVE/MMISVE.pdf?bcsi_scan_DAD819A53026B58E=0&bcsi_scan_filename=MMISVE.pdf

Vendor Evaluation scores sub criteria price level and price history

Dear all,
I have configured vendor evaluation with subcriteria price history and price level as automatis.
For test, I created a vendor and a material. Assigned market price for year 2009 and 2010.
Also info record price maintained for the vendor material combination.
Vendor XYZ
Material ABC
For 2009 Market price 8 and effective price 8.5
For 2010 Maket price 8.2 Effective price 8.5
Variance calculated 8.43% and score is 15. This was calculated correctly.
Now I created another material and maintained master data for that mater
Vendor XYZ
Material DEF
For 2009 Market price 18 and effective price 20
For 2010 Maket price 20 Effective price 22
Variance calculated 1% for which the score is 50.
When I go for vendor evaluation through ME61 , system is not considering the average of 2 scores. But giving a score of 50. Score bands are as follows.
5     Price behavior     5.0     10
5     Price behavior     10.0     15
5     Price behavior     20.0     20
5     Price behavior     50.0     20
5     Price behavior     99.0     10
5     Price behavior     5.0-     50
5     Price behavior     10.0-     100
5     Price behavior     50.0-     20
5     Price behavior     99.0-     10
Pls help me resolve the issue

Vendor Evaluation - Price history

Hi
In vendor evaluation the score for the subcriteria Price History is not getting calculated.
The scoring method that I have used is : Automatic Determ. from Purch. Statistics: Price Behavior
What can be the reason? How it is calculated?
Regards

to determine how a vendor's price for a material has changed over the last few years, the material's price history is compared with the market price history.
The system first checks whether the buyer has maintained the current market price and last year's market price for the material.
If not, the system uses the price for the material group to which the material belongs.
If this price is not maintained either, the system uses the effective prices from the previous year and the current year. Prices from standard purchase orders for materials and prices from subcontract orders are dealt with separately.
The system then calculates the percentage variance between the old and new market prices.
The vendor's effective price is re-calculated with this percentage variance. The result represents the effective price the vendor should be asking if his price had changed over time in the same way as the market price.
This calculated effective price is then compared with the actual effective price, and a percentage variance is determined.
The system then awards the vendor the score you have maintained in Customizing for this percentage variance.
The system repeats this process for all the materials you procure from the vendor. Each time you start an evaluation, the system calculates the average score for all the materials. The result is the vendor's score for the subcriterion "Price History".

Price level in vendor evaluation

Hi,
I have created 1st PO with price 50 and checked the ME63, system showed score for price level as 40. Then I made another PO with price 55 and checked ME63, system displayed the same score 40,
While there is change in price of 10 %, so I was expecting score of 10 .
Can anyone explain about this.

Hi,
Following is the calculation procedure for
1) Price Level -
If you have maintained market price for the material, the system checks vendor's price level with the market price, otherwise it compares the vendor's price with average price of material by all vendors. Then the price variance is calculated in percentage. The score is awarded for this price variance as per settings in your system configuration. This process is repeated for all the materials supplied by the vendor. The overall score is the average of all these scores.
2) Price Behaviour -
System checks market price / average price of the material for last year as well as for current year. System calculates the percentage change for the market price. System repeats this procedure for price of material by vendor. Then system compares these two values & calculates percentage variance. The score is awarded for this variance as per system configuration. The overall score is the average of all these scores of the materials.
3)Online Delivry statistics -
System calculates the difference between scheduled delivery date in PO & actual delivery date & calculates the percentage variance. The score is awarded as per settings in system configuration. This process is repeated for each P.O. & overall score is average of all these values.
Hope the answer is helpfull. For more details, you can avail online help at site http//:help.sap.com on subject Vendor Evaluation.
