Element vs Balance dimension Inception to Date

Content

Hi,

I am building a fast formula that should look at the Inception to date balance of an element.

If the same element is used 2 times for the same employee, the inception to date is accumulating, it doesn't reset once the element is closed!

What dimension should I use to be able to capture the inception to date of the current Element Entry, not all the accumulated balance for that element entry used  multiple times?

Any idea also is greatly appreciated!

Thank you
