One very common issue in MicroStrategy is problems with access. In Chapter 10, Design and Implementation of the Security Model, we learned about the security model of MicroStrategy. Sometimes, when we create a new schema object or public object, it can lack security. For example, the user could complain that they have problems with access. The best way to do it is to add a test user to the same groups as the complaining user and then try to add writes. We should read error messages; they can give us the direction to search for the problem and help us find out what we should update.
