I am sorry, but unless we can identify what the application is, and that it is Confluence, there is not a lot we can tell you. We really need to know if "Iteraplan" and/or "Iteratec" are based on Confluence.
We could help you with a Confluence database, but if they're not based on it, it's going to be utterly useless to you.
My best guess is that their documentation is in Confluence, and you have followed a link for help with Confluence instead of a link for help with Iteraplan!
