To whom it may respond to, I got this message while trying to design a synch job for 2 different tables from 2 different databases : "Last reported error: SqlState = 42S22 NativeError = 207" [Microsoft][ODBC SQL Server Driver][SQL Server]Invalid column name 'Credit Limit'." Have modified the config file to use quotes instead of brackets , and restarted the server but no changes. http://support.microsoft.com/kb/222664 gives solutions and workarounds for that, I have tried this solution by adding the parameter to the source database parameters, maybe I did something wrong while adding that to conn. parameter of jitterbit source. Any ideas? Thank you for your concern.
