Business rule: get completed months/days of absences

[Sevda]

Hello,

We are trying to get  the calulation of the full calendar months covered during the absences (so eclude partial months). Number of months or days, no matters.

 I used the function "Get Completed Months Of Time Types In Period()", but it provides only full month for a given Time type. 

we can have two or three unpaid absences that cover the entire month, and in this case the function doesn't work.  

We would like to be able to cumulate several absences to get completed months in a period. 

Any idea how I can that? I'm pretty new on Employee Central Time.

So your help would be really appreciated.

Thank you in advance!

Regards, 

Sevda
