Top k selector per category

Hi,

I have only a few experience with Knime so is there a way to get the top k not from a whole data set but per category. The categories could be defined by the values of a specific column.

Thank you for your help,

Claude.

Hi there @claudeostermann,

in order to do so should use loop. So start with Group Loop Start where you define group columns and finish with Loop End node to concatenate results. In between you need Top K Selector obviously :wink:
