I have in the system a contract for purchase order where I have for example:
for a vendor and a material, for the next 100 pieces to buy them in price 5 euro.(catalog price 10)
Can I create a contract in order to have for the next 100 pieces 40% discount on the catalog price. This way if I change the catalog price I will not have to change the contract.
How can I do this, what are the steps??
