This would boil down to anything having to do with your stock and processes connected to it that comes under unnecessary information for you. From the standpoint of the WMS, the only thing you would not need to know is stock-related activities that have to do with other inventory owners that use the system. Of course, the same applies to your stock where others are concerned, as separation and security are essential.
In other words, you must know absolutely everything that concerns your stock while it resides in the warehouse. To that end, there is nothing that the WMS leaves out when it provides you with realtime data. If there is anything that you are not seeing, the chances are that it does not exist.
This system is designed to be a comprehensive one that feeds you with a host of insights, which makes you feel like you are almost always on site.
