Hi,
What you want to do is difficult to do in Discoverer, because you need to add the same amount into the report more than once to generate the open and close balances. Also Discoverer always returns a table of data so the columns must be the same for each row.
You can generate this report by creating a database view or custom folder that unions together the amounts for the open and closing balances.
For example, if your table was called inv_table then you can create a view or custom folder containing the following query which has some extra columns for selecting rows in your report:
select name, null inv_date, 0 num, amount, 'OPEN' sect, inv_date sdate, inv_date edate
from inv_table
union all
select name, inv_date, num, amount, 'STMT' sect, null sdate, inv_date edate
from inv_table
union all
select name, null inv_date, null num, amount, 'CLOSE' sect, null sdate, inv_date edate
from inv_tableThen you can create your report based on this folder selecting the name, inv_date, num, sect and SUM(Amount) from the folder. Create sdate and stmt_start and stmt_end date parameters for the report and then use the following conditions to select the rows you want:
(sdate < :stmt_start or sdate is null) and edate <= :stmt_end
and
(inv_date between :stmt_start and :stmt_end or inv_date is null)Rod West
