Deleting websheet Primary and Alternative reports

Question

hi,
I saved the primary report and it actually created another primary report, i am actually up to having 3 primary reports. for example when I want to add a new section to a page that includes a chart, it ask what data grid and report to base it off of, when i select the report it list 3 "primary Reports". all 3 are slightly different. how do I delete 2 of them? the checkbox for deleting them does not appear when I go admin -->manage services -->interactive report settings --> saved reports --> web application reports . it is intended behavior to be able to have multiple primary reports .
next, i created an alternative report, deleted by using the steps above....but the report still shows as am option on the data grid page, the select list for reports still includes the alternative report even though I deleted. this is a real problem as the alternative report is wrong and end users keep using it.
Thanks,

Answer 1

OK I think I figured it out. Clearing out the user preference (in the post-login block in the authentication scheme) seems to make it pick the Primary report (APXWS_DEFAULT) every time a new session is created.
Not sure I understand the syntax behind the various values I see in the preference so I didn't mess with setting the value but clearing it out seems to work fine.
DECLARE
    l_ir_pref VARCHAR2(500);
BEGIN
    -- Clear preference so that IR defaults to Primary Report
    select 'FSP_IR_'||application_id||'_P'||page_id||'_W'||interactive_report_id
    INTO l_ir_pref
    from  apex_application_page_ir
    where 1=1
    and application_id = nv('APP_ID')
    AND page_id = 10 -- Change as needed
    AND ROWNUM = 1;
    apex_util.remove_preference(l_ir_pref);
END;Is any of this documented?
