Hi Friends

recently we upgraded my SAP ECC 6.0.EHP3 system DB from mssql2005 to MSSQl2008r2, after that my sap system is working fine  but

when iam checking DB02 for Database Size History , that time iam getting warning message like No

No size history ,check job details

and SAP SQL Statistics is showing yash color symbol 

but all the jobs are working fine..

Please give me the reason for this.where i need to changes.
