Dynamic Display of report heading from Dimension Filter

Hi Experts,

In Design Studio 1.1 with Bex query as source, I need to display the report heading(Text Box) dynamically by taking the filter applied in one of the Dimension Filter.

So i have used like this - Text1.setText(DS_1.getFilterText("<Tech name of infoobject>");

When I select some value for the filter at runtime, I get both Key and Text as the report heading, but i dont want to display the Key but only the Text of the infoobject. How to control this  property ?

Thanks & Regards,

Kesavan.
