IRs with Subscriptions that might not work
If you have an Interactive Report with the Subscription feature enabled, users can “subscribe” to the report, getting a daily email with the results of the report. Unfortunately, however, this feature doesn’t work as expected if it relies on session state – e.g. if the query uses bind variables based on page items to filter the records. In this case, the subscription will run the query with a default session state – APEX doesn’t remember what the page item values were when the user subscribed to the report.
This is a query I used to quickly pick out all the Interactive Reports that have the Subscription feature enabled but which might rely on session state to work – i.e. it relies on items submitted from the page, refers to a bind variable or to a system context:
select workspace, application_id, application_name, page_id, region_name, page_items_to_submit from apex_application_page_ir where show_notify = 'Yes' and (page_items_to_submit is not null or regexp_like(sql_query,':[A-Z]','i') or regexp_like(sql_query,'SYS_CONTEXT','i') );
For these reports, I reviewed them and where appropriate, turned off the Subscription feature. Note that this query is not perfect and might give some false positives and negatives.
