Last period as initial value but still have period as parameter?

Hi all,

I'm using an olap cube in a report (dash board).
The last "actual" period should be viewed when the user opens the report. I'm using the MDX tail function for that.
Once the report is opened the users want to select another period. Then I want to put period as a parameter.
But that is not possible since the parameter check box is no longer available when using a MDX filter expression.

Is there any solution to this problem?

Any help will be appreciated.

If you know MDX, then don't use the query designer and just write your own queries. You'll need to have 2 maybe 3 datasets:
