DSS
Central, Satellite & Remote - Error 3057: Variable could not be
converted to a valid number
This
error may occur when transferring files from an FTP site using
TeleMagic's DSS Dial Up Server. The FTP site being used is either
not set to UNIX-style directories, or there are files in the directory
which do not use the 8.3 file name convention.
The solution is to change the FTP server directory type to UNIX
format, and make sure all files located in the affected directories
(even if they are not related to Data Synchronization) follow
the 8.3 file name convention-no more than 8 characters plus an
optional 3 character extension.
