Yet another interesting situation where we had to display an Report on Excel and put it on SharePoint Power pivot gallery. We selected the Cube database and dragged in a few dimensions and Measures along with a few slicers. The query that was auto generated was not very optimized.
The report was to show data only for last one week. One of the slicer "Week Starting Date" was to have dates for the last one month only.
We had to use some hidden filters to ensure that we show only part of the data. i.e. only last 4 weeks data. There are few ways (Slicer Settings) where we can visually indicate that Items that do not have data should be disabled (will be shown) and also there is a way to move those items to the end of the slicer. There is no way of removing that altogether.
In such situations we can write a custom query to only fetch data with Week Starting Dates that is within the last one month range. This also improves the performance because of the optimized query against the Cubes.
Excel do not provide a direct way to update the query. There are a few Adins/products that aid to this, like Vivid http://www.varigence.com/products/vivid/features/navigation that will come into handy.
Another approach could be to use an ODC File where you can embed the MDX query. I am attaching a sample ODC file. Pay close attention to the highlighted section.
