Score problem in vendor evaluation for sub criteria Quantity Reliability...

Hi Experts,
For the subcriteria Quantity Reliability i have calculated the score like below,
pur.order quantity - 1000.
receipt qty - 900.
var = 900-1000/1000 *100 = 10%.
10% var = 90 pts.
old score - 41
new score -90
smoothing factor - .30
41 * (1-.30) + 90 * .30 = 56. Am getting,but
system calculates 59.how.Is there any configuration problem.
I hardly need to solve this.pls anyone help me.
Thanks in advance.

Hi,
to answer your question satisfactorily we need to knwo about more details.
what are the minimum delivery factors, overdelivery and underdelivery tolerances?
these all are considered in the score calculations.
to adjust the score the system gives high priority to average score that is 1-smoothing factor.
if you have just updated the score for same delivery then the score calculation is different.
in case of further queries please find the MMSIV document you could find it in some fo the posts.
you will get some more information in one of my earlier posts.

Vendor evaluation points automatic criteria

Hi
How the percencetage & points are determined for automatic criteria.
Regards

hi,
Vendor Evaluation for Purchasing
Go to SPRO --> Materials management --> Purchasing -
> vendor evaluation
Define the weighting keys in SM30 - V_T147J.
Weighting keys 01 and 02 are defined in the standard system. You combine the following
weighting shares for the standard main criteria:
Main criterion Key 01 Key 02
Price 1 5
Quality 1 5
Delivery 1 2
Gen. service/support 1 1
Ext. service provision 1 2
Define the criteria in SM30 - V_T147G - Double click on the line items
In this step, you define the criteria by which the system computes scores for vendors and
specify whether the scores for the subcriteria are computed manually, semi-automatically, or
automatically.
You can also store your own methods of computation for the scores for subcriteria in the
form of user exits. The enhancement MM06L001 is available for this purpose.
Define the scope of list in SM30 - V_T147M - Double click on the line items
Define Purchasing Organization data for vendor evaluations in transaction OMGL.
An example :-
How the system calculates the score for the automatic subcriteria
"On-Time Delivery Performance"?
The system uses the statistics-relevant delivery date in the purchase order
(Items -> Delivery Schedule) and the goods receipt date to calculate date variances.
You use the statistics-relevant delivery date, for example, if you know that the vendor
will not deliver the material as scheduled on September 15 but on September 30. Enter the
delivery date as September 30, but enter the statistics-relevant delivery date as
September 15.
In calculating the score for on-time delivery performance, the system will then not use
the actual delivery date, but the statistics-relevant delivery date. This has a negative
effect on the score for this goods receipt.
However, materials planning and control uses the realistic delivery date (September 30)
which the vendor will actually adhere to.
The system considers only goods receipts against purchase orders and scheduling agreements
into stores and the release of GR blocked stock into stores. In the standard system, these
are the movement types 101 and 105.
Minimum Delivery Percentage - OMGL in the On-time delivery section
If you do not want a vendor to receive a very good score if he delivered the goods on time,
but did not deliver the required quantity, you can maintain a minimum delivery percentage
in Customizing.
Assume you set the Min. del. perc. parameter to 60% and the vendor delivers the goods on
time, but only 55% of the ordered quantity. Although the goods receipt is punctual, it is
not included in the calculation of the vendoru2019s score for on-time delivery performance. So
that the non-scoring of the on-time delivery performance criterion in this case does not
bring an unfair advantage in comparison with a poor score, the vendor is awarded a low score
for quantity reliability. On-time delivery performance is thus always to be seen in
conjunction with quantity reliability.
Standardizing Delivery Date Variance - OMGL in the On-time delivery section
To rate delivery date variances in days, maintain the Std.del.time var. parameter.
If you assign a lower standard value, this means that relatively low date variances produce
high percentage variances. If you set a higher standard value, this results in a relatively
low percentage variance:
The Std.del.time var. parameter has the value 20. The goods receipt took place on Nov. 27;
the statistical delivery date was Nov. 15. There is thus a difference of 12 days.
The system calculates the percentage variance as follows:
12 / 20 x 100 = 60
If the Std.del.time var. parameter had the value 60, the variance would be 20%
(12 / 60 x 100 = 20).
If you do not maintain this parameter, the system calculates the delivery time variance via
the firm zone in the case of scheduling agreements, and via the order date and the
statistics-relevant delivery date in the case of purchase orders

Perform VENDOR EVALUATION for MORE THAN ONE VENDORS at a time

Hello all,
Please guide for any process where i can perform Vendor Evaluation for MORE THAN ONE vendors AT A TIME.
At my location there are around thousand vendors, which are to be evaluated, and difficult to perform the evaluation process one-by-one.
(ME61/ME62/ME63)
Detailed replies with various possibilities would be highly appreciated.
Thanks & Regards,
Joy Ghosh

The vendor evaluation for some thousand vendors at the same time has already been in SAP long before they developed LSMW. The purpose of LSMW is to load data from a legacy system, of course you can (mis-)use it for a lot other things.
But you should not always use LSMW if you are to lazy to go thru the SAP standard menu to find a transaction like ME6G
There you define a job that runs RM06LBAT report.
You first have to define a selection variant for this report. this can be done in SE38 by entering the report name, select variant, clicking display, then entering a name for the variant and clicking Create.

Vendor evaluation using Invoice criteria

Hi SAP gurus,
I want to know if anybody has used de Invoice criteria in Vendor Evaluation, that is available in ERP 2005.
The subcriterias Price Variance and Quantity Variance are automatic?
Can we use them only with MM Module or do we need the SRM functionalities?
Thanks in advance.
Best Regards,
SN

Hi
In invoice main criteria we have
- Quantity variance
- Price variance
Quantity Variance
With this criterion, you evaluate how exactly the quantity to be invoiced agrees with the quantity actually invoiced.
Price Variance
With this criterion, you evaluate how exactly the price to be invoiced agrees with the price actually invoiced.
In order for evaluation results for the two last-mentioned subcriteria to be generated automatically, you must activate invoice evaluation for the company code. In the process, you also define the maximum points score per company code.
You can refer the documentation

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

Problem: Run Time Evaluation for Future Period

Hi SAP Gurus, can someone help me solving this problem:
My client need to run time evaluation for 2-months period ahead of time. But every time I tried, time evaluation always stops at end of the current month, no further dates in the future. I had created attendance data 2002 for all the future dates. IT7, 2002, 2006 and all configurations seem to be OK (T510S,T569R). Test run is also OK with good future results. What could possibly be missing? Thank you in advance.
Bill

Thank you very much, Arun, Banu, Stefan and Om.
Yes, I have entered the "Evaluation up to" date (60 days later);
The schema has a function "Check FUT".
Test future run result was generated correctly.
Still I can't have future results in real run.
So, what else I should check into?
Thanks again.
Bill

Vendor evaluation at material level

Hi friends,
I have one requirement from client. A vendor supplies many materials. My client want to get report of vendor rating of the vendor for each material and material groupwise.
Can this objective can be achieved?
Please suggest.

Hi,
When you run Vendor Evaluation (for all criteria), sysytem keeps log of all material level points the Vendor has achieved. You can view the same in transaction ME64.

Additional sub criteria for Vendor Evaluation tab in SES (ML81N).

Hi,
I like to add two additional sub criteria for Vendor Evaluation tab in SES (ML81N). Based on which vendor evaluation will be calculated.
1. Safety/Envt Upkeep
2. Morale
These two are added in SPRO->Purchasing->Vendor Evaluation ->Define Criteria. But not displayed in ML81N->Vendor Evaluation tab.
Existing criteria. 1) Quality of Service and 2) Service Timeliness are already available.
Thanks in advance.

Hello Chetan,
have you checked note 79166 "MM-SRV Hint: Vendor evaluation for service"?
Define an evaluation criterion for services in Customizing of the vendor evaluation to be able to use the vendor evaluation also for the services management.The main criterion must contain the determination methods 'C' (determination from the quality valuation of the service) and 'D' (determination from the timeliness rating of the service) in the sub-criteria.

Vendor Evaluation With Non Standard Main and Sub Criteria

Hi Gurus
I have a requirement wherein I have to evaluate a vendor on non stanadard Main Criterias like
1. Productivity with sub criteria as Receipt / Excepected Yield, for which I have used Scoring method 2
2.Quality Standards with Sub Criteria,- Germination (%),Genitic Purity % , Field level flags, for which i have used scoring method 7 by activating user exit- MM06L001
3.Raw Seed to Clean Seed ratio, with the same sub criteria and with the above scoring method and user exit.
The weightages given to the above three are 40 , 35 and 25 respectively.
Can you please tell me how to calculate the values for subcriterias( for example for my main criteria 2. i want to assign the weightaghes for sub criterias - Germination - 50 , Genitic Purity %- 30, & Field level flags - 20, . along with smoothin factors.
I want to automise the whole process and run the evaluation in the background.
An early reply will be very helpful to me.
thanks and regards

Vendor evaluation - Quantity Score for Service Items

Hi experts,
Vendor Evaluation is active in our client system.
There are both material and service vendors for score evaluation.
One of the service vendors is having a Quantity Reliability (Delivery criteria) score of 100.
Only services (item cat SERVICE) is procured from this vendor.
The On-Time Delivery performance score is 0 (not calculated).
Why is Quantity Reliability set to 100 if all material documents are related to service items?
Anybody face such issue before?
Plz provide your inputs..thanks!

Hi.
You need to configure Output type NAHN (Dunning). Define condition records. Follow the same steps as you configure PO output type NEU.
Make sure the 1st/2nd/3rd reminder days are maintained n PIR.
These days are displayed in Delivery Tab of the PO.
If the above output type is determined, then a standard SAP batch job automaticall ryns ME9F to send reminders /expeditors to the vendor. You dont have to do any other config for this
