I'm desperate, I don't know is something wrong with data, formula, or just me.
I have to tables Calendar (dates) and Item Ledger entry (item turnover data), they are related by Calendar[Date] - Item Ledger Entry [Posting Date].
The result should be table wich shows some other measures (sales data) regarding date filter and a colum in the end [ Stock]. Stock shows how much items we have left to last date of filter (it ignores first filter date). First of all I must calculate commulative total, and just stuck here.
