Node-level Calculations / Top-Down Planning

Hi,

I am working with SAP BPC 10 MS and am trying to input values on node-level Elements, in order to perform adjustments on a top-level (node-level) basis.

My intention is to catch the values which have been written to the node within an INSTEAD OF SQL-Trigger.

The trigger then should simply take the node-level value and do some calcutlations, in order to spread the node-value to the underlying base members.

Howeverthe node-level values do not even get passed to the INSTEAD OF Trigger, but are filtered by SAP BPC before they get passed to the Database.

Is there a way to make the SAP EPM AddIn (or maybe the SendGovernour) to pass node-level values to the Database?

Thank you very much for any ideas,

Kind regards

Marco
