Need help on uploading different types of files using the IBM iSeries Data Transfer utility. I hear you can use the .FDF definitions created from a download containing the same fields you want t upload. I just don't know how to use the .FDF to update the data. I'm using v5r4 iSeries. I'm interested in learning how to upload .TXT and CSV files. I did upload a file and got three fields, two of which were SRC fields. I eventually want to use the files uploaded as databases that I may query.
