Field Mapping

[priscila]

Should I have to set Field Mapping every time for upload & download Database or one time ?

You have to do field mapping if your headers do not match those in SS and if your file name is a new file name. For example, if you always call your file upload.txt and the headers are always the same, map once, and that is all you should have to do in the future.
