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 Criterion 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 R New overall vendor rating
Current R Current overall vendor rating
New period R New overall rating for the current criterion
Old period R Old overall rating for the current criterion
Factor Specified 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)
Rating The rating for the criterion per period.
Value The total value, the total quantity or the total number of purchase order lines for the criterion per period.
Sum All 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.

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

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.

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
