One of the challenges of creating reports is finding the data that you are looking for.  This is especially challenging if you are working with a very large and complex database, like an ERP system.  So if you have to create reports against a Lawson database, you might want to check out lawsonguru.com.  They provide an online copy of the searchable structure documents called dbdoc and dburf, and they have this for several versions of Lawson.  They also have some forums and a job posting board.  Some areas require a (free) registration.
