Hi,
I have a requirement where I need to schedule(batch processing) a report.
I create a report with the required datasource and the respective data set.
The report is executed as per the schedule and the resultset is stored in
the temporary table.
How can i retrieve the resultset later from this temporary table using
this report. The dataset associated with the report would point to the
source table. Is there any way I can fetch the data from this temporary
table without changing the dataset associated with this report.
Can I also store the information i.e. the datasource name and this
temporary table name somewhere in the report so that I can fetch the
values any time later.
Any pointers will be appreciated.
Regards,
Anirudh

The Data Extraction Task is part of the BIRT API. If your not familiar
with the BIRT API programming, this might be a little confusing :)
Basically, when BIRT runs a report, there is an file generated called a
report document that contains all the data for the report and all the
elements, it just hasn't been rendered to its final output yet. With
this file format, you can do things like specify multiple output formats
in a single pass, read the table of contents, and extract the data.

Yes, you can add, modify, or manipulate a data set to be used during run
time. You can do that internally using BIRT scripting.
