Time passed between multiple values in a data item

[superdesi]

I have a data item that returns multiple date values based on how long a person has worked in a certain department.  I want to calculate how long that person has stayed in that department before moving on.



In the above example I want to calculate months between July and November.....and then November and January....and so on.

If the data item "Date" returned one date at a time, I know how to go about that......but this multiple value has me stumped.

Thanks in advance.

Hi,
Easiest way will be section the list by Employee and sort ascending by Date and use running-difference([Date]) and derive the days or months from it. Another way is to create a function and import it and then use it in the report.
Good luck

Thanks for the tip on sectioning it.  Didn't think of that.

However.....i have no clue on creating a function.  Thanks again.
