Hi @Aliyaharu , and welcome to the KNIME community. The Ranking node can do this for you. For an example see this post:
You will need at least two columns in your original data table to work with the Ranking node. You will make the Order Number your “grouping attribute”. If you don’t have a second column to use as the “ranking attribute”, simple create a new column prior to calling the Ranking Node, eg you could use Counter Generation, and then use that column as the ranking attribute.
