If you have a lot of views, best practice would be to check to see if any of your data sources in any reports contain a field with a certain name like "CustomerID". The code sample below is an example of how to accomplish this.

public bool FindColumn(ReportSet reportSet, String columnName)
        {
            foreach (JoinedTable jt in reportSet.JoinedTables)
            {
                if (AdHocContext.Driver.DatabaseSchema.FindColumn(jt.TableName   ".["   columnName   "]") != null)
                    return true;
            }
            return false;
        }
       
        // Customize a report on the fly prior to execution on a per user basis
        public override void PreExecuteReportSet(Izenda.AdHoc.ReportSet reportSet)
        {
            bool found = FindColumn(reportSet, "ProductName");
        }
