Principal Component Analysis: Group by 2 columns

Dear ONE DATA users,

I want to apply the “Principal Component Analysis” processor. To do so, I need to group my data table by 2 columns. In the config of the PCA processor, I identified the option “GROUPING COLUMN” for grouping but it is a singe-select. Is there a possibility to use the processor and group by 2 columns?

Thank you!

I never used the PCA processor but maybe it is an option for you to merge your two grouping columns into a single column (e.g. by concatenating their content) and then select this single column as a grouping column in the PCA processor config
