Diagnosis
The current time stamp, minus the safety marginInt.Ext.Gn that you created in the backlog setdefinition table produces the time: (Date &V1&, Time &V2&).
This point in time, however, is before the previous evaluation
( Date &V3& , time &V4& ).
In this case, the system evaluates the period
( previous evaluation - today ) = ( &V3& &V4& - today )

Caution
There is no guarantee that all logs in this period are evaluated sincesome mass runs that produce these logs could still be running.
You may have to start extra extract generation runs for the sameperiod in order to include missing extracts in the error extract table(INSTSET).

Procedure
SAP recommends that you wait a few days between two runs. This ensuresthat all logs to be evaluated are up-to-date and completed. You can alsoavoid having to repeat runs, and the danger of some incorrectinstallations not being included in the error extract table (INSTSET).
