I’m using your pakage datatable.Activities for a group by and sum all the values.
I have a DT1 with 5 columns but then I use your aggregation sum, I aggregate column “Amount” ; Groupe by “Name”.
How ever the dtResult is only this 2 columns but I need the DT1 with all the columns.
How is it possible ? Could you please help me out ?
Thanks in advance
HI @najoua.abbaci ,
Use the Group by aggregation .
