If you upgrade to 7.4 most of these titles attributes have ben made much bigger - 255 chars. If you mods the DB directly there is stuff you also need to fiddle with to let LDSD know that change has happened and if you ever run MDM these altered values get reset to the values MDM 'knows' is best. Ideally 7.4 would be your best route IMHO.
Ok, thanks for the reply.
I also have a question to this topic.
are these change also implemented on the system stuff, like Customer Group Title?
Because a customer of mine, discovered the issue, that these fields are limited to 100 characters.
