I also checked the issue raised by Ella which the file from the MD system sent to the Pentaho sftp server is always zero in which we are not able to check because the server is in Japan (I think). I also mentioned that we can only check if the file was received but was not uploaded in Pentaho that is when we check on our side but beyond that, we will not be able to check why the file we received in the sftp server is zero.
