title: SSIS Copy files task does not copy custom date column
body: <p>Well, I am facing one weird issue with Copy Files task i SSIS.</p>
  <p>I have folder A in which I have sub folders and I am using Copy files task to copy all the Excel files in sub-folders to the folder A. I noticed that with some of the excel files where I have custom date column which is restricted by list to select dates from as I don't want user to input wrong date/format.</p>
  <p>When I run the package the excel file is copied but that date column is not getting populated.</p>
  <p>I am not getting the reason why its happening.</p>
  <p>Can some one help? What approach I should follow to resolve it?</p>
