This error can occur if ART does not get the CDR data to report.
In order to determine if there are any records in the Structured Query Language (SQL) database, complete these steps:
Choose Start > Programs > SQL > Enterprise Manager > Microsoft SQL Servers > SQL Server Group.
Choose Publisher Server > Databases.
Choose CDR > Tables. Right-click the CallDetailRecord table.
Choose Open Table > Return All Rows. Determine if there are any records.
If many records appear, complete this procedure to remove records from ART:
Choose Programs > SQL Server > Query Analyzer. Log in and choose ART database.
Run these queries:
delete from Tbl_Load_History
delete from Tbl_Dump_PkID
delete from Tbl_Error_Id_Map
delete from Tbl_Billing_Data
delete from Tbl_Billing_Error
delete from Tbl_Dump_CallDetailRecord
delete from Tbl_Dump_CallDetailRecordDiagnostic
This forces ART to get all the old CDRs into ART in the next scheduled loading time. By default, CDR data is loaded every day from midnight to 5 a.m.
Restart the CDR Insert and DBL Monitor Services from CCM Administration > Application >Cisco CCM Serviceability >Tools > Control Center.
