I am running Knime 5.3.1 version, most of the time under classic UI.
I have multiple table that I would like to join into a Table Row to variable loop start.
So I would like to dynamically setup the join columns.
I have tried to manage a Flow variable for both Left & Right table as a List.
But when I get into “Configure Flow variable” , i can’t choose such type of Flow Variable. Only option is a single string. See the capture below :
But, it is possible in the "SelectionConfig as illustrated below.
In my remember, in old version it was possible to specify variable List into LeftPredicate or RightPredicate.
Did I miss something ?
Is there a different way to do the same ?
Many thanks in advance for all the help you can bring.
Hi @edphi , and welcome to the KNIME community forum. I didn’t see your message from 10 days ago, but I just spotted it whilst responding to a new and similar question. You are not alone!
