One way to do this is to use indirect sources. You can configure your session to use indirect sources, wherein the source file names are coming from a text file (each entry in the listfile is a source file session will read).

Then you can arrange your code to add that dynamic filename to that listfile.

The source file name in my project starts with a number for example 20070908abcd.csv. Informatica is not allowing to read the source in the designer and displays the following message:
The first character in this name cannot be a number.

Could you please let me know how to handle as many source files are of this format?

I have a mapping like
SA-->SQ--->EXPR--->TGT

The source will be of the same structure and the tartget also.
There are a bunch of files(with the same structure) which will go through this mapping .
So i want to use a parameter file through which i will give the file names for every run manually.

How to use the param file in session for Source filename attribute
Please suggest..
