Group aggregated data using date slicer

Hi,

I tried to get a solution here: https://community.powerbi.com/t5/Desktop/Remove-0-from-balance-list/m-p/1150852

But I try to reframe:

Is it possible to create something like a group by that can be altered by a slicer?

Let me show you the table [Daten]

It is easy to get the balance list:

But I need to get rid of all account numbers that have a "saldo" of 0.

A filter is of no use because on row level, there is no 0

So I thought it would be helpful if there was a possibility to create a virtual table where all values are grouped by account number. 

And if I change the selected date (slicer) the grouping also changes.

It would be easy to create a grouped table, but I want to know the "saldo" in a specific time period. (2019, 2020, 1-5 2020... )

do you think this is possible?

thanks a lot!
