In order to meet the ISO standards, you need to set up a procedure for the entire vendor rating and score calculation methodology.
The vendor rating process is activated or deactivated for each individual supplier. If you have not activated the vendor rating for a supplier, the vendor rating forms will not be available for that supplier. The ratings are determined on supplier level and not on creditor level.
When determining the purchase lines to be included in the rating process, Isah looks at the actual delivery date. Partial deliveries are added up, and the value of the 'Date delivered' field will be set to the date of the last delivery. The supplier must confirm all purchases by delivery date, and not by delivery week.
Rating criteria are defined for individual purchase lines. All scores, limits and percentages are without decimals. If you change the description of a criterion after you have already started using the vendor rating process, the old description of the criterion will not be maintained in the ratings.
