It really could be anything "transactional", not structural (in an ALM Deployed model). For instance, if this is in a data hub, it could be different validations of your data to ensure you are not missing and cost center/department/meta data that is currently defined within the transactional data or it could be different mappings that need to be defined, or Dynamic Cell Access. Essentially, items that can only be changed/updated by an admin and not an end user.
1. Import errors, one eg is text items that could not find a mapping. Another eg is missing or invalid parent items. 2. Trend of data over time on a high aggregate level. This will help to indicate if something is going wrong in data directionally. 3. User access control, if you wish. 4. Action to clear or reset lists. 5. Admin managed mappings, subsets.
Having said this, its really the business case that drives the content of admin dashboard. I just gave some which are very generic, not essentially needed for everyone.
Something I had made for myself that can be very useful depending on your model: an archive module where I would copy the whole P&L (works with every final reporting module you have) and then check against the live calculation for any difference. I'd make a copy before starting some development this way I would know in a glance if a change I was doing had any impact at all on calculations.
