Dear Experts ,
In vendor evaluation I have maintained Score for On time delivery as mentioned below.
| Percentage | Score | |
| On-time del. | 0 | 100 |
| On-time del. | 20,0 | 60 |
| On-time del. | 50,0 | 5 |
| On-time del. | 99,9 | 1 |
| On-time del. | 5,0- | 95 |
| On-time del. | 50,0- | 20 |
| On-time del. | 99,9- |
Now I have created a New PO for a new vendor & have done the GRN as mentioned below
| PO Doc date | 18.10.2012 |
| Stat Delv date | 27.10.2012 |
| GR Date | 03.11.2012 |
Delivery Variance is = PO Stat Delv Date - PO Doc Date = 9
Hence % = (GRN date- Stat date ) * 100/ Delivery Variance
= 7 *100/9 = 77.7%
Hence Score should be 1 .
But system is calculating score as 60 !!. I am quite clue less on the calculation front. Please suggest.
Best Regards
