    Absence overlap

      We have a requirement to allow overlapping absences. I have defined two different types of absences; Vacation and Flex. Both have accrual plans and I want to allow absence overlapping functionality for these. When I created these absences, I selected the radio button option as 'Yes' for Allow Absence overlap.

      When I enter two different absences with the same dates as below, I am getting a message that the dates are overlapping.

      Type:Vacation Absence
      Start date 13-feb-2013
      End Date 13-Feb-2013
      Absence Additional Details (ABS_INFORMATION3) = Half Day
      Saved successfully

      Type: Flex Absence
      Start Date 13-Feb-2013
      End Date 13-feb-2013
      Absence Additional Details (ABS_INFORMATION3) = Half Day
      Unable to save as I am getting an error message that the dates are overlapping. Shouldn't the system allow this when I select the Allow option for absence overlap?

      The reason why we want to allow this is we have a policy where employees can take half day absence. They can take two half days on the same day with two different absence types.

      Is there a better way to address this requirement?
      Thanks a lot for your help..

          My assumption was that it would warn you but still save.
          But why not create hourly leave instead (based on hours not days)? Half day would be 4 hours based on 8 hour workday.

          I wrote a function to check hourly absence overlaps as well which you can use in your bg_absence_duration_formula.

          p_assignment_id in number,
          p_start_date in date,
          p_time_start in varchar2,
          p_time_end in varchar2)
          return varchar2
          v_overlap_flag varchar2(500) := 'N';
          v_overlap_count number := 0;
          v_time_start_dec number := 0;
          v_time_end_dec number := 0;
          -- get time start and time end as decimals
          ((to_number(substr(p_time_start,1,2))*60 + to_number(substr(p_time_start,4,2)))/60),
          ((to_number(substr(p_time_end,1,2))*60 + to_number(substr(p_time_end,4,2)))/60)
          into v_time_start_dec, v_time_end_dec
          from dual;
          when others then
          return 'N';
          -- find absence
          select count(paa.absence_attendance_id)
          into v_overlap_count
          from per_absence_attendances paa, per_absence_attendance_types paat,
          per_all_assignments_f paaf
          where paa.absence_attendance_type_id = paat.absence_attendance_type_id
          and paa.person_id = paaf.person_id
          and paaf.assignment_id = p_assignment_id
          and p_start_date between paaf.effective_start_date and paaf.effective_end_date
          /* check if absence time start and time end are in between */
          and (p_start_date <= paa.date_end and p_start_date >= paa.date_start)
          and ( (v_time_start_dec between ((to_number(substr(paa.time_start,1,2))*60 + to_number(substr(paa.time_start,4,2)))/60)
          and ((to_number(substr(paa.time_end,1,2))*60 + to_number(substr(paa.time_end,4,2)))/60))
          or (v_time_end_dec between ((to_number(substr(paa.time_start,1,2))*60 + to_number(substr(paa.time_start,4,2)))/60)
          and ((to_number(substr(paa.time_end,1,2))*60 + to_number(substr(paa.time_end,4,2)))/60))
          when no_data_found then
          v_overlap_count := 0;
          when others then
          v_overlap_count := 0;
          -- if no overlaps found
          if (v_overlap_count = 0) then
          v_overlap_flag := 'N';
          v_overlap_flag := 'Y';
          end if;
          -- return flag
          return v_overlap_flag;

            Thanks igwe.

            For some reason, absence overlap feature is not working even if I select that while defining the absences. I tried lots of options but still no positive outcome.
            I have logged an SR with Oracle to see what they have to say.
