Pass parameter value from dimensional treeprompt to report based on rel. package

[blom0344]

Is it at all possible to pass a value from a dimensional treeprompt to a report based on a relational package? The query behind the tree prompt consists of just one item:

rootmembers([DMR Model].[Consolidationstructure].[Consolidatiestructure])

I tried passing the _businesskey  and the memberunique name to a relational report, but nothing is passed through the drillthrough definition..

Am I missing a clue?

Sorry for opening up such an old thread, but after 2,5 years I uncovered an interesting piece of documentation:

http://public.dhe.ibm.com/software/dw/dm/cognos/reporting/prompts_and_filters/tree_prompt.pdf

I am trying to get this to work, but  the  rootMembers function dos not return any members in a tree prompt whereas validating the expression does show members.

My definition:
rootMembers([namespace].[dim_name].[hierarchy])

made it work using the Descendants function.  I have researched the passing of Dimensional prompt values to a relational model for quite some time, and now it works after an afternoon fiddling  :D
