I want to sum qty for a range date . the following expression is wrong:
sum( {<dealdate={">=min({<data_origin={'purchase'},dealdate={'<=$(=$(var_date1))>=$(=$(var_date2))'}>} dealdate)"} >} qty)
or
sum(if(dealdate >=min({<data_origin={'purchase'},dealdate={'<=$(=$(var_date1))>=$(=$(var_date2))'}>} dealdate),qty)
First I must find a the min date for type of 'purchase' , and sum the sales's qty from that date.
