Query Regarding Combining Models on KNIME


We are trying to combine 2 regression models built on KNIME for one of our use-cases. For this, we need the identifier feature of the data set, to be able to combine the results of the models. Is there a way to set the identifier feature in KNIME, please let me know.

Thanks in advance.

Not entirely sure what you mean by identifier feature. If you mean a unique ID you could use the RowID or set a variable as RowID

If that is not what you are looking for maybe you could provide a sample workflow (with dummy data) that shows where the problem is.
