Bring in percent of rows by RowID

I have files that I create RowID’s based upon concat of two columns. From these RowID’s I need to bring in a percent (10) of each RowID. This works great if I have over 10 of the same RowID and will bring in appropriate number of records. But I want to make sure and bring in at least 1 record of each RowID. How to I capture these RowID’s that have under 10 records in them?

Hello,

Could you share the workflow and sample data? I’m wondering what part of the workflow doesn’t work for this project. Thanks.
