Hi,

We are facing an weird issue with the Drill Through. So, we have made all the configurations in correct way and data loaded correctly and drill region definition created correctly …etc. (do not doubt anything configured incorrectly, we have searched around all oracle document/internet posts that you can find or suggest to read…:)) The issue is, when trying to do the drill through from planning webform/smartview adhoc back to DM, only several accounts can successfully drill back and show the data, all other accounts failed saying no drill region is available.
