I create this global temporary table and create a form, where I am calling report through a push button but report isn't showing records.
Kindly advise me, how to use global temporary table in reports.

-------------------------
-- GLOBAL TEMPORARY TABLE
-------------------------
create global temporary table PROD_INV
(
WDATE DATE,
DOCNO VARCHAR2(10),
CUSTM VARCHAR2(7)
)
on commit preserve rows;

-----------------
-- CALLING REPORT
-----------------
Run_Product(REPORTS, :Global.Report_Path || 'SD_PRODINV', ASYNCHRONOUS, RUNTIME,FILESYSTEM, pl_id, NULL);

It is a very long time since I worked with Forms and Reports 9i, but I think you will find that the report is run by a different session, so it can't see any rows inserted by your Forms session.

By the way, please try to avoid saying "record" when you mean "row" Smile

A workaround might be populating the GTT in report's After Parameter Form trigger, if possible. For example, if you used a (stored) procedure in a form, you can call it from the report as well - you'd just pass required parameters. Or, if you can distinguish which records you want in the GTT and have a mechanism (i.e. WHERE clause) to do so, report can easily do it as well.

Otherwise, you might need to discard the GTT idea and return back to a "normal" table (and include some kind of an identifier which will prevent two or more users reading the same data).
