RE: AX query - sorting with sum field

Hi

I think your sequence is incorrect.

Try this

qbds.addSelectionField(fieldNum(RetailTransactionTable,netAmount),SelectionField::Sum);  

qbds.addGroupByField(fieldNum(RetailTransactionTable, CustAccount));  

qbds.addSortField(fieldNum(RetailTransactionTable,netAmount),SortOrder::Descending);
