If the Crystal Reports check box has been checked you should here enter the file name of the report file (.rpt) that will be used.
If the report files have been saved in the folder Monwin\CRYSTAL\standard or Monwin\CRYSTAL\custom, it is sufficient to enter the file name here. But if the report file has been saved somewhere else you should enter the entire file path, for example \\server\shared folder\file name.rpt.
