Vendor Ratings by Criterion (tdpur8102m100)

Use this session to maintain and to display vendor ratings by period and by criterion.

Only if the criteria type is Subjective, more than one criterion can be displayed. Otherwise, LN displays only one criterion for each criterion type.

When LN calculates the overall vendor rating with the Update Vendor Rating (tdpur8850m000) session, the period ratings for a business partner are also stored in this session. In this case, the Criteria Type field is Period Rating.

If you change the vendor rating, the following recalculation takes place:

  • If the method to calculate the overall vendor rating is Smoothing Factor, LN recalculates the overall vendor rating as follows:

New R = Current R + (factor * (new criterion R - old criterion R))

New RNew overall vendor rating
Current RCurrent overall vendor rating
New period RNew overall rating for the current criterion
Old period ROld overall rating for the current criterion
FactorSpecified in the Vendor Rating Parameters (tdpur0100m800) session
  • If the method to calculate the overall vendor rating is Moving Average, LN recalculates the overall vendor rating as follows:

New R = sum of (rating * value) / sum of (value)

RatingThe rating for the criterion per period.
ValueThe total value, the total quantity or the total number of purchase order lines for the criterion per period.
SumAll criterions that apply to the business partner are taken into account. You can specify the number of periods, that are taken into account, in the Vendor Rating Parameters (tdpur0100m800) session.

You can calculate the vendor ratings on a monthly basis. For example, if you fill in the year 2000 and the period 11, this represents November 2000.

Period

Criteria

The subjective criterion for which LN displays the vendor rating.

Adjusted Rating

The vendor rating for the business partner/year/period/criterion combination.

The rating is initially calculated by the Update Vendor Rating (tdpur8850m000) session. You can only change the calculated rating, if you are an authorized user.

The vendor rating that is stated in the Adjusted Rating field, is taken into account when calculating the overall vendor rating for the business partner/year/period/criterion combination.

Note

If you manually change the rating, and then update the vendor rating, LN takes the changed rating into account. As a result, you do not have a proper overview of the vendor rating for the period/criterion combination.

So, if you consider it necessary to change the vendor rating manually, you should change it at the end of the period, after the vendor rating for the period/criterion combination is updated for the last time.

Computed Rating

The initially calculated vendor rating for the business partner/year/period/criterion combination.

This rating is calculated by the Update Vendor Rating (tdpur8850m000) session.

You can use this rating to see which ratings are changed in the Adjusted Rating field and what is the original value of the changed ratings. So, you cannot change this rating.

This rating is not taken into account in any calculation.

Total Value

The total turnover of all purchase orders that are processed in the Process Purchase Orders (tdpur4223m000) session and that fall in the specified period. LN retrieves the data used for calculating the total value, from the Purchase Order Line History (tdpur4551m000) session.

Note

The total turnover in this field is always calculated.

If the Weighting Method field of the Vendor Rating Parameters (tdpur0100m800) session is Turnover, the total turnover is taken into account in the calculation of the rating for the business partner/criterion/year/period combination.

If the Weighting Method field of the Vendor Rating Parameters (tdpur0100m800) session is Piece Count or Order Lines, the turnover value is not taken into account in the calculation of the rating.

Total Quantity

The total quantity of all purchase orders that are processed in the Process Purchase Orders (tdpur4223m000) session and fall in the specified period. LN retrieves the data, used for the calculation of the total quantity, from the Purchase Order Line History (tdpur4551m000) session.

The total quantity is expressed in the inventory unit.

Note

The total quantity in this field is always calculated.

If the Weighting Method field of the Vendor Rating Parameters (tdpur0100m800) session is Piece Count, this total quantity is taken into account when calculating the rating for the business partner/year/period/criterion combination.

If the Weighting Method field of the Vendor Rating Parameters (tdpur0100m800) session is Turnover or Order Lines, the total quantity is not taken into account when calculating the rating.

Total Number of PO

The total number of purchase order lines that are processed in the Process Purchase Orders (tdpur4223m000) session and fall in the specified period. LN calculates the total number of purchase order lines, based on the data as entered in the Purchase Order Line History (tdpur4551m000) session.

Note

The total number of purchase-order lines in this field is always calculated.

If the Weighting Method field of the Vendor Rating Parameters (tdpur0100m800) session is Order Lines, this total number of purchase orders is taken into account when calculating the rating for the business partner/criterion/year/period combination.

If the Weighting Method field of the Vendor Rating Parameters (tdpur0100m800) session is Turnover or Piece Count, the total number of purchase-order lines is not taken into account when calculating the rating.

Changed By

The employee of your company who changed the value of the Adjusted Rating field.

Default value

LN automatically enters the name of the employee who changed the value of the Adjusted Rating field.

Overall Vendor Rating

The vendor's overall rating.

Vendor Classification

You can classify the ratings by different classes instead of showing the raw ratings. You can assign a one-letter code to each class. So, you can have A grade vendors.
