Hi Folks,
is there a simple solution, to filter the rows processed by the stage macro?

Thanks for your response,
Kind regards,
Matthias

Might be a good idea for enhancement: allow an optional parameter in the yaml metadata of the stage called filter_source_by and allow the user to add a statement as the input.
We can add this to the list of features to be developed for enhancement, but I can't give a timeline on when it will be done as we have other features in the pipeline.

Kind regards,
Barbara
