Hello everyone,
I'm trying to reproduce the example "050002_CreditScoring" but I encounter problem with the reproduction of the metanode "Nominal to Numerb". In the attachment i have put a screen capture in qich you can see the error and the workfloe design. Moreover, in the attachment there are two Workflow, "050002_CreditScoring" and "KNIME_project3" (my reproduction). I can't understand why this message of error appears:
"WARN GroupBy Group column 'Status of existing checking account' not in spec."
In the workflow made by myself, I don't encounter the problem until I run the node "Loop End (Column Append)". I think the problem is in the node "GroupBy" but I can't find the solution.
Any ideas?
Thanks for the help
