I have two queries: 1 that pulls a list of codes and values, and the second that extracts data based on the code.

The code/value table uses the values as a drop down list. Both values and codes are strings.
When the Value is selected, the code goes into the second query that becomes the data-basis of the report.

The problem is that the dropdown works perfect in PRD, but fails with ServerBI.
All aspects are strings, no integers or numbers involved.

When the user is in Server BI, and the dropdown is selected, the error I get is:
ERROR [AbstractReportProcessor] 98499519: Report processing failed.
org.pentaho.reporting.engine.classic.core.ReportParameterValidationException: The parameters provided for this report are not valid.

How do I troubleshoot this? Like I said, it works perfectly in PRD.
