Segmentation - Value helps for ADS table

Hello,

I have an ADS table for segmentation based on objects that is loaded from BW. Is there a documentation on how to create value helps for use in the Flex Segmentation tool? I tried to use, for example, the CITY_PART value help, but instead of showing the "City part" and "City" fields for search, the system shows the fields "Filter" and "Description". I tried to use them but it doesn't obtain de expected results.

Thanks!
