On Supplier Agreement Assortments on Supplier Agreement page, you can change the additional cost for a supplier assortment in a purchase agreement. The additional cost is a cost you must pay for each purchase order line of the supplier assortment. The cost is independent of the quantity ordered.
If you are using supplier assortment step pricing from the amount of zero, it is not necessary to change the information according to this activity. Instead, you should follow the instructions in the activity Enter Addition for Supplier Assortment Step Pricing, since a supplier assortment step pricing always overrides what is stated in the purchase agreement.
Supplier assortments are entered in a purchase agreement instead of entering multiple parts having the same terms regarding discount and additional cost. Of course, the direct price cannot be specified. No-number parts can also be included in a supplier assortment and thereby be included in a purchase agreement.
The new additional cost is retrieved to applicable purchase order lines for the supplier assortments. If you want these new terms to be valid for purchase orders which you have not yet sent to the supplier, you must remove the old lines and add new ones.
