Whenever you need a number from a system you should think of how you can create a report, so next time you can press a button to get the result.
If you found yourself doing ad-hoc reports, or random SQL queries, a few years ago, the best thing to do was to make sure the boss knows you could not find the data you needed, so he could commission a new report to be built.
The best practice is to jump into Power BI and build the report yourself.
