I am reading a series of .txt files from a directory. There are two separate file layouts which need to be applied, so I filter first to segregate. Then, using the dynamic input, I use one of the files as the template for the data to read in all the matching data files. I want to have the original filename as part of the output file downstream. When I use the Dynamic Input, I'm losing that field. Is there a way to capture the name and have it on each row of data from the source file?
