Hi again @arkiboys . So if I understand right, you just want to get pipeline name and some details from copy activity, and write this to a parquet using another copy activity and the 'additional columns' feature.
When I do something like this, I do almost the same, except for source I point to an almost blank delimited text file. By almost blank, I mean it only has whitespace. This way, the only real contents will be the 'additional columns' feature.
