DAC : Task PLP_AbsenceEventFact Failed

Question

Hi all,
I have a task which fails during Incremantal Load because the variable $$LAST_EXTRACT_DATE is empty in the SrcFile parameter.
$$LAST_EXTRACT_DATE=
$$LAST_EXTRACT_DATE_IN_SQL_FORMAT=
$$LAST_EXTRACT_DATE_WID=
$$LAST_TARGET_EXTRACT_DATE_IN_SQL_FORMAT=CONVERT(CHAR, '2011-02-26 14:52:05', 120)
I don't understand why this variable is empty and not equal than the variable $$LAST_TARGET_EXTRACT_DATE_IN_SQL_FORMAT like the other tasks and how to solve my issue.
Thanks,

Hi,
this variable is defined in the Source System Parameter and if I see a SrcFile Parameter for a SDE Mapping, the $$LAST_EXTRACT_DATE_IN_SQL_FORMAT is defined.
And in a Full Load, the load runs fine and the SrcFile Parameter has the $$LAST_EXTRACT_DATE_IN_SQL_FORMAT.
The Session Log error is :

I just see that the source table are empty because the bsence Module is not implemented in EBS. Maybe it is the source of the problem.
Thanks,
