A SIte subcommand was entered with an SBDATACONN parameter that specified a file name, but FTP was unable open file. The SBDATACONN parameter is ignored.
FTP continues.
Ensure that the file name specified on the SBDATACONN parameter is a fully qualified name of an existing MVS™ data set or z/OS® UNIX file.
If the file name is correct, look in the FTP server's trace for the reason why FTP cannot open the file.
