0TCT_C21 Process Chain statistic over night

Hello,

I have some problems with a Query.

I'm currently trying to display all our process chains with the duration of them.

This works fine, expect if the Process chain runtime is over a new Date ( => Start Date 04.12.2012. End Date 05.12.2012)

I would like to see on the 05.12.2012 a duration of (54+135) = 189 min and no entrys for the 04.12.2012.

Is that even possible without changing data on the 0tct_c21.

Or how do you guys handle this situation i don't see any good way for this.

Best regards,

Timon
