Why is the KPI not showing Daily data and always referring to Monthly aggreate table?
If the KPI is a cross tab KPI, the KPI must be configured in such a way that the 'Month' is used in the cross tab. Therefore, it always refers Monthly level aggregate table irrespective of the filters you select in the KPI. In short, in order to view the daily level data for this KPI, please re-configure the KPI by removing the 'Month' from the cross tab.
