Adherence to Conf. Date (Main Criter. "Delivery") 

Use

This section describes how the system calculates the score for the automatic subcriterion "Adherence to confirmation date".

Prerequisites

You can define the type of confirmation to which this subcriterion relates, e.g. transport confirmation, loading confirmation, or shipping notification.

Minimum Delivery Percentage

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 vendors score for on-time delivery performance.

Standardizing Delivery Date Variance

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.

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.

Activities

This section describes how the system calculates the extent to which a vendor adheres to a delivery date he has previously confirmed (in this case, using an Inbound Delivery on the basis of a shipping notification as an example).

Scores are calculated in the same way as in the case of on-time delivery performance.

 

 

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.
