Refresh Interactive Report Definition via PLSQL

Question

Hello!
I am currently working on set of generic database-apex applications.
That means I have two applications. The first is the admin apex application used to define columns and tables.
The second application is the one for the end users, where they can view and edit the values.
My problem now is: Every time the admin adds or removes a column I need to edit the user-apex application, open the region definition of all interactive reports and switch to the report attributes to add/remove the columns of the report.
I would like to automate this step via plsql. How can I achieve this?
I guess the first step would be to load a list of all IRs...
select * from apex_application_page_ir where application_id = 133;
But I don't know how to reload the columns...
Can anyone help?
Thanks in advance!

Hello Andre, Hello Mimi!
Thank you for your messages.
First to your idea Mimi, i think you brought me on the right track. Using your update statement doesn't works for me.
There are some missing permissions I couldn't grant and in addition I think this would hardly work because apex_application_page_ir is a complex view.
But I am currently working on a solution using the wwv_flow_worksheet_standard.synch_report_columns function. Code like this:
DECLARE
l_flow_id NUMBER (20);
l_region_id NUMBER (20);
l_query VARCHAR2 (4000);
l_result VARCHAR2 (4000);
BEGIN
SELECT application_id, region_id, sql_query
INTO l_flow_id, l_region_id, l_query
FROM apex_application_page_ir
WHERE page_id = 9 AND application_id = 133;
APEX_040100.wwv_flow_worksheet_standard.synch_report_columns (p_flow_id => l_flow_id,
p_region_id => l_region_id,
p_query => l_query,
p_add_new_cols_to_default_rpt => 'Y');
COMMIT;
END;
Unfortunately it doesn't work. When executing the synch_report_columns procedure the following error raises.
ORA-01003: no statement parsed
ORA-06512: at "SYS.DBMS_SYS_SQL", line 1685
ORA-06512: at "SYS.DBMS_SQL", line 629
ORA-06512: at "APEX_040100.WWV_FLOW_WIZARD_API", line 840
ORA-06512: at "APEX_040100.WWV_FLOW_WORKSHEET_STANDARD", line 2735
ORA-06512: at line 23
Maybe you or someone else can reproduce the error?
Therefor you simply need an interactive report on a page, based on a view. Remove some column of the view definition-the IR will display an error like this:
ORA-20001: get_dbms_sql_cursor error ORA-00904: "DUV_FOCUS_OFFSET": invalid identifier
Then execute the code above (use your page and app_id).
After the execution the IR should work again. In my opinion...
@Andre: The application I am working on is a critical pice of software used in a highly sophisticated semiconducter fab.
It is simply impossible to train some of the shift leaders or operators on apex, in fact it is a great thread if someone else can change the application and produces a downtime.
So for me it is necessary to script everything as far as possible. I finished nearly everything, simply the synch of the report columns is missing...
