Issue when Structure is added

Hi All,

I am having an issue where the query brings in Blank rows,(the characteristics are populated, the key figures are blank)when more than one characteristic is added in the column structure.

If I remove the structure the query works fine, and only when one characteristic is added to the column structure also it works fine. But the minute I add a second characteristic to the column structure, it throws in rows with balnk values, which should not be there.
