how to change timestamp format in file receiver

Hi all,

I have a FILE to FILE scenario WITHOUT repository objects.

What I need to do is to add a time stamp at the end of the target file.

By default, the "Add timestamp" option in the file receiver communication channel makes the filename as *YYYYMMDD-HHMMSS-xxx

What I need to have is the date&time format as MMDDYY_HHMISS.

Are there any modules by default in SAP PI in which I can manipulate this stuff? Or is there other way to do this?

Thanks in advice!

Regards,

Claudio
