Pass non-database parameter from report to form

Question

(Portal 3.0.9) In short, how do I pass a non-database parameter into a form?
I am calling a single form from multiple reports. On successful submission of the form, I want to return to the calling report. I have built the dynamic "go" statement in the success submission portion of the form:
declare
return_to_report varchar2(30);
begin
return_to_report := p_session.get_value_as_varchar2(
p_block_name => 'DEFAULT',
p_attribute_name => 'A_CALLING_REPORT');
go('<portal_schema>.'||return_to_report||'.show');
end;
The problem is that I'm unable to populate the "calling_report" field in my form since it is non-database and does not appear in the list of available variables in my link.
Also, it would be better to pass the value (report name) in a session parameter or global variable so that it is not tied to a specific record in the form, but I cannot find documentation for help.

Hey,
You could also create your own link in the SQL statement.
SELECT
display_link_update(asset_seq) as Update_Record,
column2,
column3,
from table
display_link_update is the function call and I'm passing one variable, asset_seq. Now the function can do the link creation and pass the link back to be displayed on the report.
CREATE OR REPLACE FUNCTION "PROPERTY"."DISPLAY_LINK_UPDATE"
(asset_seq1 in varchar2) return varchar2 is tag varchar2(4000);
begin
tag:='Update Link';
return tag;
end;
I need to check out session variables. Do a Google search, there should be a few items about it. I'll look into in a few days beacuse I should learn this myself.
