Sap can't calc overtime for more than 24 hours in a day

Question

Dear experts,
I'm having problem currently with overtime, because of the following condition
1. The employee worked on saturday (let's say this was 9 jan 2010) and monday (10 jan 2010) where in both of those days, the employee should not work (FREE Work schedule)
2. The employee worked from 09.01.2010 at 6PM until 10.01.2010 at 8PM (26 hours)
3. we're using time events, so the clock in and clock out are noted in IT 2011 with the following :
    -in:09.01.2010 6PM
    -out:10.01.2010 8PM (but with assigned to prev day indicator set)
4. The overtime approval using IT 2007 is defined using this one record :
    -begda:09.01.2010     endda:10.01.2010
    -time:6PM - 8PM.
5. We can't separate the overtime entry in 2011 into two separate record, because of progressive rate of overtime. (i.e for first 10 hours of overtime, you get $10, for the next 10-20 you get $20, and so on)
However the resulting time evaluation only calculate overtime from :
09.01.2010 18.00.00 - 20.00.00 (2 hours)
10.01.2010 42.00.00 - 44.00.00 (2 hours)
for total 4 hours,
We've tried :
1. creating two of 2007 record for :
     -09.01.2010 6PM-00.00 (6 hours)
     -10.01.2010 00.00 - 8PM (20 hours)
    => result : only the first six hours were taken into account
2. create one  2007 record for :
    -09.01.2010 - 10.01.2010, with time 00:00 - 24.00
    => result : we got 26 hours. However the attendance quota shouldn't contain full day time (00:00 to 24:00), because if the employee fill the 2011 with more than he/she should eligible, he/she will get those also.
3. create one 2007 record for :
    -09.01.2010 - 09.01.2010 with hours : 26 (using unit instead of time), but if the time contains minutes (such as 18:02 or 20:18) this will needs to be calculated manually, which will be a hassle.
where what we need is total 26 hours, with using attendance quota, than can span days, but without filling manually the hour. Or perhaps something similar. Any idea how to achieve that in SAP ?
Thank you.

Answer 1

Hi,
this reply is related to option 1 as mentioned in your post. Can't tell for 100% whether the following makes any sense as I have never recorded overtime in IT2007. (I normally use IT2002).
But in most of my previous projects where not all recorded overtime was calculated, this was often to a missing selection rule in T554S.
