Panel: How I get the measure name out from Datasource based on BW

Hello

I like to build a Panel with following:

Name of measure, value, unit, scale

value = DS_1.getDataAsString ("KPI", "Filter");

unit =  DS_1.getDataAsString ("KPI", "Filter").unitOfMeasure;

scale= DS_1.getDataAsString ("KPI", "Filter").scalingFactor;

How I get the Name of the measure out: ??

Thanks
