I have a dataprovider report with 4 tables, thus 4 datasets pointing to a single data provider class. I actually have 2 other reports that are similar and those work fine.
When executing this report I get an error:
An error occurred during report data sets execution.
Event viewer reveals the error in the subject.
I have:
- Restarted IIS
- Restarted SSRS
- Model build and database sync
- Product build
- VM Restart
- Deleted, and Redeployed the report.
- Changed the SRSReportDataSetAttribute declarations from tableStr to just hardcoded strings and vice versa.
- Deleted all datasets, and recreated them.
- Decreased the size of the name of the tables
I'm not sure what else I can do but the reports do not run. When I debug data is generated successfully in all tables.
