deletion.criteria-guid? SAP BI4.1 SP01

Hi,

I see the below error frequently appearing in Windows Event log. Does any one know what is this "deletion.criteria-guid"?

does this delete any files from the FileStore? We are unable to access some of the scheduled report output files so wondering if this could be the cause.

Could not open the File

\\..\\FileStore\Input\a_xx\000\xxxx\deletion.criteria-guid[8d8d..].list.

Thanks,

Ravi
