Hi there. I have a data table which contains mappings of topics to categories, e.g:
Y | Z | |
A | Yes | |
B | Yes | Yes |
Where'Yes' indicates the topic belongs to the category.
I want to unwind this table to a list of pairs of topics and categories like this:
Topic | Category |
A | Y |
B | Y |
B | Z |
And possibly call a REST service for every pair. I'm not quite sure how to go about this in Knime, will I need to use workflow and loops?
