Quick payment discount condition in SAP is activat

When the customer has a finance agreement like 2% discount when they pay after x days the net price in QuoteStream is including this 2% payment discount in the quotation to show the final price to the customer.
Then when the customer buys the product, the 2% discount for quick payment is applied on the invoice (again)
So the customer gets 2 times 2& discount.
. 1 time because QuoteStream has integrated it in the quote
. 1 time because SAP applies it on the bill (again)

Solution:
1. Identify the condition name for quick payment discounts
2. Exclude them from QuoteStream? Possible? Can we find a way?
