The cause

[
    SRSReportQueryAttribute(queryStr(CustAccountStatementExtBaseData)),
    SRSReportParameterAttribute(classStr(CustAccountStatementExtContract))
]
public class CustAccountStatementExtDP extends SrsReportDataProviderPreProcess
{
    CustAccountStatementExtTmp custAccountStatementExtTmpNew;
    boolean giroCreated;
}

The Solution

In Visual Studio, select the dataset that the report uses (CustAccountStatementExtDS) and set the property 'Dynamic Filters' to false. This will cause the data map to be re-read.

Then rebuild and redeploy the report.
