How to create report which do sum of fields with group by

Dear All,

I am creating a stock report with two data items : 1st data item is Item Table & 2nd data item is Item Ledger Entry Table, then i created DataitemLink on item between both tables.

Now i want to show current stock in report so i added required fields on body sections of Item Ledger Entry, but report showing multiple entries vide single article. I already added itemno of ILE in Value of GroupTotalFields to show single article. But it is showing all entries from ILE vide single article.

Please help me.



Use all fields on Footer Section
