HI,
create the new formula -> quantity -> hit the aggregation tab -> summation/total -> reference char -> 0CALDAY - it will give no of days for each customer
you want total quantity of each customer -> create the new formula -> quantity -> exception aggregation tab -> counter for all detail values that are null or zero -> reference char -> customer
it will give the customer wise give total quantity.
try the above scenario.
put the 0calday, calmonth at free char panel.
customer in rows panel.
Thanks,
Phani.
