Extending reports to support more rows

Question

Hello,
I have a report that returns more than 2000 rows, which seems to be the default number of rows for reports from grid control. I have experimented with creating this report using the mgmt_ip package because there is a element parameter that can be specified to extend the row limit. However, when I run my script, the report shows up in the mgmt_ip_* tables, but not in the gui.
Is it possible to create a report this way without adding it to a package? If so, how can I do it? Also, is there a better way to get more than 2000 rows returned?
Thanks,
M

Thank you for the suggestion Caroy. Unfortunately the complete data was requested in a particular format by my managerial team and there was no changing their minds. I was able to accomplish this task by running the mgmt_ip package directly against my repository instead of packing it up into an extensibility package. I used a modified version of the example laid out in the extensibility documentation. Here is what I used:
BEGIN
DECLARE
l_report_title_nlsid VARCHAR2(128);
l_report_owner VARCHAR(100);
l_report_guid RAW(16);
l_param_values MGMT_IP_PARAM_VALUE_LIST;
l_element_guid RAW(16);
l_curr_order NUMBER;
l_curr_row NUMBER;
BEGIN
l_report_title_nlsid := 'report title goes here';
l_report_owner := mgmt_user.get_repository_owner;
l_report_guid := mgmt_ip.create_report_definition (
p_title_nlsid => l_report_title_nlsid,
p_description_nlsid => 'insert description here',
p_owner => l_report_owner,
p_category_nlsid => 'main catagory here',
p_sub_category_nlsid => 'sub catagory here'
l_curr_order := 1;
l_curr_row := 1;
l_param_values := MGMT_IP_PARAM_VALUE_LIST();
l_param_values.extend(4);
l_param_values(1) := MGMT_IP_PARAM_VALUE_RECORD(
'oracle.sysman.eml.ip.render.elem.TableRender.numRowsToShow',
'999'
l_param_values(2) := MGMT_IP_PARAM_VALUE_RECORD(
'oracle.sysman.eml.ip.render.elem.sqlStatementIsPlSql',
'false'
l_param_values(3) := MGMT_IP_PARAM_VALUE_RECORD(
'oracle.sysman.eml.ip.render.elem.TableRender.maxNumberOfRowsAllowed',
'20000'
l_param_values(4) := MGMT_IP_PARAM_VALUE_RECORD(
'oracle.sysman.eml.ip.render.elem.sqlStatement',
'sql goes here'
l_element_guid := mgmt_ip.add_element_to_report_def (
p_report_guid => l_report_guid,
p_element_name_nlsid => 'IPMSG_USER_TABLE_FROM_SQL',
p_element_type_nlsid => 'IPMSG_ANY_TARGET_TYPE',
p_element_order => l_curr_order,
p_element_row => l_curr_row,
p_parameters => l_param_values,
p_targets => null
END;
END;
The downside to this is that it is created as a locked system report and cannot be deleted without directly modifying the underlying tables. There is an additional setting that can be flagged to stop it from being created this way and it is outlined in the extensibility documentation, but I never revisited this task to test it out.
