Hi Friends,

        My scenario is File(FTP server) to File( BW Al11). This is Pass through Scenario.

  1.I want pick two files from FTP server  1 file pick every wedns day and 2nd file pick every day.

  2.File name having timestmap. I want Pick that files and put the file in Archive with time stamp and at the same time i want put the file in IN folder       without time stamp.

    is it possible to  do this in One Interface?

    is it possible file name changes in pass through scenario( Using NFS)?
