maybe someone has an idea

I have two tables. One table contains 15000 destinations with a total of 230 orders. Each order occurs any number of times, so that in the end there are 15000 destinations (orderlines). Then I have a second table with 15000 lines. It contains 40 articles and their withdrawal quantities. The articles occur several times. The most frequent article occurs 200 times and the rarest article only 3 times.

Now I want to join both tables so that no article appears twice in any order.

How can I realise this in knime?
