Dear knime users,
I have a hierarchical organized list, I like to create a workfow which allows me to switch between the hierarchical levels. The grouping works fine to me, but not the ungrouping.
GroupBy ID2 - for Aggregation “Concatenate” and “;” as delimiter.
Alternatively I used the GroupBy with “Unique concatenate”, this yields
I guess with the “Unique concatenate” information for the ungrouping gets lost?
However, now I want to reverse the workfow to yield the initial format.
Since the ungrouping has to be done with many columns, the “Cell Splitter” “Ungroup” approach did not work for me.
