We have a need to report on historical data when none exists in the database. Has any tried anything like what follows successfully? Or are there other ideas out there?
- Create a tabular report rdl that is run on a regular schedule. This report run is saved as an Excel sheet that overwrites the previous run, which has the same name.
- Report is designed to use two data sources--the database and and the previously run Excel sheet. The data is "merged" using the Lookup function thereby creating a new report that includes the history needed.
Thoughts? Thanks!
