if you can help or advise me it would be great.

I have installed OTRS 3.3.8 on CentOS 6.5 and configured as my company wanted and it's working great.
Because OTRS doesn't have reports, I'm using excel pivot table and exported *.csv file to get some statistics, but I have founded that is possible to connect directly on MySQL base of OTRS trough Connector/ODBC for Excel, but I'm having problem with reading data from it.
When I select all tables from OTRS MySQL database it's only showing data from first table.
Does any of you using this way of getting data from OTRS? or maybe have some idea how to connect and read all data?
Thanks.
