I have a header file and a data file with no headers that I need to merge in order to profile. I'm attempting to merge them in the tool however I am having trouble. I was hoping there is a way to add the header within either Analyst or developer to save me the time of a manual process. The files are tab delimited and are a 1 for 1 overlay. Right now the data file is over 7gb and not able to be added easily.

Why don't you just run a script in the server to cat the two files together. Will be much easier then having to use a mapping. You can even insert the header row directly into the data file so you are not trying to copy the 7G into another file. Much easier.
