'Previous Version' Table on API Refresh

[CLeDane]

I manage a Power BI tool that is linked to my company's CRM database which tracks and forecasts potential business identified by managers. I have this report scheduled to refresh every week and automatically distribute. I would like to create a view that shows the difference between our forecasted numbers since the last refresh.

Is there a way to program Power BI to clone the current data into, say, a "previous version" table everytime the report is refreshed? Then I could use measures to find the differences I want to report from those two tables (the newly refreshed data, and the previous version data)?

I have a manual workaround, but if this could be automated it would make me look really cool 🙂

Power BI doesn't have that. Nor should it (in my opinion) - I think it is better to do that versioning further upstream.  

Ideally you don't want to do snpashots. Better if you can record just the changes between snapshots (which would require a unique opportunity ID). Much, much better if you could actually do this event based, ie record all changes to your data as they happen.

Snapshots are plagued by the Nyquist-Shannon distance.  Event based records are not.

Not sure what your CRM system is, but Salesforce.com (for example) has event based record keeping baked in.

The CRM system is Dynamics. Thanks for the reply, I expected as much.
