add a suffix number at the end of the values

[ScottF]

Hi @psycho -

Am I mistaken, or isn’t this question very similar to one you posed previously? Can that solution be adapted to this one?

Add an auto incrementing number loop generator for a column

I need to get id column(in red colour) if the unitID is duplicating adding 1 value to it and then 2 and then 3 and so on. Could somebody help me with this this? [image] KNIME HELP.xlsx (9.9 KB)
