Issue:
When running a report, the following error message is displayed:
The given key was not present in the dictionary
Cause:
Jet Reports caches certain information about the table structure, unique identifiers, and fields available in your data source when a Data Source Connection is first accessed. When that information is changed (for example: a new primary key is defined), the cache needs to be refreshed.
Resolution
Either:
- Restart Excel, reload your report, run your report
- Open your Data Source Settings, click OK, run your report
