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 vendor’s 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.

  • Delivery subcriteria for Vendor Evaluation

    Hi
    How are the scores computed for the subcriteria in Deliovery?
    Regards
    Soumen

    Hi,
    Delivery criteria is comprised of following Sub-criteria;
    - On-time delivery performance
    - Quantity reliability
    - Compliance with shipping instructions
    - Confirmation date
    On-Time Delivery Performance: - This subcriterion is used to determine how precisely a vendor has adhered to the specified delivery dates.
    Quantity Reliability: - This subcriterion is used to determine whether a vendor has delivered the quantity specified in the purchase order.
    "On-time delivery performanceu201D and u201CQuantity reliabilityu201D always have to be seen in conjunction. You can specify for each material (in the material master record) or for all materials (in the system settings) the minimum quantity of the ordered materials that must be delivered in order for a goods receipt to be included in the evaluation. This enables you to avoid a situation in which a punctual goods receipt involving only a small quantity of ordered materials is included in the evaluation with a good score for u201Con-time delivery performanceu201D. If this minimum quantity is not delivered, the vendor is not awarded a score. However, in this case the vendor receives a bad score for quantity reliability.
    Compliance With Shipping Instructions: - This subcriterion is used to determine how precisely a vendor complies with your instructions for the shipping or packing of a material.
    Confirmation Date: - This subcriterion is used to determine whether a vendor adheres to a previously confirmed delivery date (that is, whether the goods are actually received on the date previously confirmed by the vendor).

    Hi,
    Computing scores for DELIVERY, minimum delivery percentage and the standardizing value for delivery time variance are taken from the material master record(In purchasing value key) or from the fields : Minimum delivery qty. in percentage and Standard del. time variance fields in Txn: OMGL.
    1. You maintain minimum delivery percentage, if you do not want a vendor to receive a very good scoreif delivered goods on time, but not the exact qty.
    2. You maintain Standard del. time variance, to reate delivery dates variances in days.
    *% variance= (Difference between Statistical delivery date & GR Date)/Standard del. time variance 100.
    Hope this helps!

  • Vendor evaluation on JIT delivery

    In case of JIT scenario how vendor rating on delivery, as schedule lines are dynamically changed in past and future.
    Does this mean that for a JIT scenario vendor is suppose to be delivering on time? And rating could be affected. Is there sufficient justification for this functionality not being available? Most of the automotive industry works on daily JIT schedules.  Clients say that it is important for the on-time and quantity reliability of vendors to be evaluated based on Goods receipt against JIT call. How vendor evaluation can be performed based goods receipt using JIT call.

  • Mapping Ontime delivery requirement in sap vendor evaluation

    Hi,
    Have below requirement for calculating score for ontime delivery performance.
    1. Evaluation will be executed weekly once
    2. For the given weekf if18 are on time out of 20 total, then the vendor gets a 90% on time score
    Tried mapping this
    1. By making std.delivery date variance as 0
    2. Maintaining points as below
    0          100
    99.9      1
    but the above settings are not working. With the above settings, system is not even calculating the on-time delivery performance.
    with this I realized that maintaining  std.delivery date variance(at least 1) is mandatory for SAP.
    Can I one guide me how to map above requirement.
    Thanks in advance

    Hi,

My recommendation is to check the attached link, it details how the scores are calculated with reference to the config you have created. Just rolled out vendor evaluation in my organisation and this document was very useful.

  • Vendor Evaluation - Statistical Delivery Date

    Hi,
    The statistical delivery date is an important field during the calculation of the on-time delivery score. (see note 310666)
    After implementing a new support package this field wasn't filled up automatically anymore. Fortunately note 1039344 and 1164767 helped overcome this.
    But ... in the meantime purchase orders were created and received without a statistical delivery date.
    Which date / or what does sap do when calculating on-time delivery score if there is no statistical delivery date ? Does it take the "delivery date" into account ?
    with regards

  • Reg: Vendor Evaluation - Criteria "Delivery"

    Hi Gurus,
    I am in process of vendor evaluation in system. Confguration is maintained and I am opting for Automatic vendor evaluation and our interest is in Price and delivery. When I am doing Vendor evaluation in ME61,
    I am getting the automatic values for Criteria "Delivery" and subcriteria  "Price Level" "Price Behavior".
    But incase of delivery I am not getting any values. I checked for settings in confirguration but not able to trace why the delivery vendor evaluation is not happening.
    Pls advice on this.

    Hi
    There are some settings like minimum delivery percentage which needs to be fulfilled for calculating score with respect to delivery performance.
    Check the PDF from the link, it gives you more details on how score is been calculated for each criteria and customizing settings

  • Vendor Evaluation / Rating

    All SAP Gurus,
    I want to evaluate number of vendors (but not all) at a time, how it can be done?
    Regards,

    Hi Ranjan,
    Vendor Evaluation component helps you select sources of supply and facilitates the continual monitoring of existing supply relationships. It provides you with accurate information on prices, and terms of payment and delivery.
    The standard SAP System offers you a scoring range from 1 to 100 points, which is used to
    measure the performance of your vendors on the basis of five main criteria.
    We can determine and compare the performance of your vendors by reference to their overall
    scores.
    The main criteria available in the standard system are:
      Price
      Quality
      Delivery
      General service/support
    These four main criteria serve as a basis for evaluating vendors from whom you procure materials.
    External service provision
    This main criterion serves as a basis for evaluating those vendors you employ as external service providers. 
    The first thread in MM contains a Pdf on Vendor Evaluation which gives a complete infromation
    Hope this basic infromation helps you out
    In case of any further clarification do get back
    Please reward in case if you find this information is found useful

  • Vendor Evaluation Standardizing Delivery Date Variance

    Hi,
    We are determining what the settings should be for On-Time Delivery and Quantity Reliability under Vendor Evaluation.  I understand how the formual works when it determines the scores for these.  Can someone tell me from a business process perspective what Standardizing Delivery Date Variance relates to? 
    Ours has been set to 100 which is 100 days with the scores set as:
    Percentage
    Score
    0
    100
    10
    90
    20
    95
    100
    80
    200
    60
    300
    40.......
    When we pick 100 days, is that supposed to be an average of how many days late goods receipts are?  Or is there another way to look at it? 
    Thanks
    Beverly

    Have you really read the documentation and the F1 field help, or any of our blogs, documents and wikis here in SCN?
    The table that you presented above is far a way from reality. a percentage can go from blank  to 99.9  and your from -99.9 to blank
    this is to cover both situations early deliveries and late deliveries
    the Standard Delivery Date Variance means the it is the maximum number of days a vendor can be late or early to the wanted delivery date, if this value is reached, then he just missed the point in the sense of the word. he does not get any single point for his performance.
    You have to ask your business how much days variance they accept before they cancel the order, or at least looking for a new vendor with the next order.
    From our point of view everything beyond a week is not at all acceptable and results in a total miss
    and in this case you do not need many percentages either in a 5 working day week  each day corresponds to 20%

  • Vendor Evaluation Delivery Subcriteria Shipping Instr and Adher to Conf Date

    Hi experts,
    I have Vendor Evaluation configured for Delivery subcriteria Shipping Instr and Adher to Conf Date.  These are set to scoring method 6 and B respectively.  In the Purchasing Org Data, for subcriteria Delivery, I have equal weighting set for all 4 subcriteria (on-time del, quantity reliability, shipping instr, and adher to conf date).  When I run the vendor evaluation in ME61, and look at the evaluation of subcriteria, I see a score and weight for on-time delivery, and quantity reliablity.  But for shipping instructions and adher to Conf Date, there is no score and the weight is 0.0.  Does anyone know why there is no weight shown?  I know I have to maintain the scores for shipping instr and adher to conf date but I should see weight as 25% since I set these 4 subcriteria to equal weighting.  Can anyone help?  Thanks!
    Regards,
    Julie

    Hi,
    As an example its not available, nor tried self. As a common rule - if a main criteria created and sub criteria exists, when you run evaluation for main - excluding a stage of sub is not possible.
    Secondly try transaction code: ME6C
    Help says: Set this indicator if you only want to display those vendors that do not have
    an evaluation for certain main criteria. When you click on Execute, a screen allowing you to choose one or more main criteria appears. The missing evaluations for these criteria are then listed.
    here you can selection option to include/exclude evaluation.

Maybe you are looking for
