What is the method of loading 5 flat files of having same
structure to a single target and which transformations I can
use?

Answer Posted / arnab

Use Union transformation , if you do not want to use Union
and if your informatica runs on Unix , then create a shell
script to concatenate these files and create a single
file , you can call this shell script before you call the
session in the workflow

If you use windows create and dos batch script and do the
same as above
